As I said elsewhere, I'm not saying "stop working on Lera" - that's the last thing I want you to do.
The problem I think is with your approach. Like I said, it's kinda like showing abstract art to a bunch of artists who paint real landscape views - there's not really much they can say about it other than "um, I like what you did with the colours?"
.
Our ability to take your work seriously is somewhat hampered by the names you give the worlds - frankly, most of the ones on your "upcoming worlds" list sound like Pokemon
. And some are just plain silly ("I like Eggs", again). Right off the bat, that's more likely to make people roll their eyes and ignore your work instead of attract them to look at it.
So you say you want to people to say what they think of the quality of your textures. Well, we can't really do that very well given that your universe has made-up physical laws. We can't say "your coastlines need to be more crinkly in the polar regions", because you could just turn around and say "ah, they're supposed to be all rounded like that because that's how it works in my universe!". We can't say "but a rocky surface on a planet can't be lurid green like that" because you'll say "ah, but this one is in my universe!". And there's absolutely no point in vetting your descriptions for realism because (a) because this board isn't really for discussing fantasy physics and (b) you'll only say "well, it works like that in my universe". We've already done that with your barycentre moon, and you still went ahead and put it in anyway. You could for example have a large rocky planet in your system that rotates once every five minutes, which would break up because of rotational stresses in our universe - but that'd be fine in your fantasy universe because you say so. If we say "hey, that doesn't work", you would just say "well, it does here". Hence there's no point in commenting on those aspects. See the problem?
What's left to comment on other than that? Not much really. Most of us want to make realistic worlds, because Celestia is designed for that purpose. All there is after that are subjective opinions on whether your worlds are like shining jewels in the fictional sky, or whether they make people want to claw their own eyes out (and I must admit that some of the colour schemes you use tend to make me want to do the latter. Lurid green polka dots on a planetary surface texture are an affront to humanity as far as I'm concerned
).
Most people who make fictional systems here do so with the physical laws of our universe in mind. Some - like Don's - are just awesomely detailed and are so realistic that they make people go "Wow, I'm so THERE!!". You can't get that effect with a system that has no rhyme or reason to it (other than what you make up), and that doesn't conform to what anyone expects to see out there. So right there, without that common reference frame, you've lost people.
What you could do is experiment and get some odd results. What if you had a world with multiple ring systems at different angles that intersected eachother (I dunno if you can even do that in Celestia)? The ring shadows would look pretty wacky on that. I used to draw worlds like that when I was a kid (and IIRC the jovian that the planet in the movie "Pitch Black" was orbiting had a ring system like that). But even then, the best response you'd get is "that looks cool, in a weird way". Don't expect Chris to add things to Celestia because of that, because that's not the direction he wants to take it (which is why you won't see green or purple stars by default, either).
My advice would be to carry on. You're obviously keen on working on it. That's fine. But don't keep saying "hey! I've finished a new addition to my system!". Just keep working on it til the whole thing is finished, and then stick the complete system on the Motherlode for people to grab if they want to. Post updates to your Lera thread if you want, but don't expect that people will read or comment on it. I'm sure some will, but it's hard to judge any system when it's nowhere near being finished.
If you want help with making a specific texture or a problem while you're doing that, then by all means post on the relevant board. But skip all the story and background reasons, because they're just not relevant - particularly when they're not even based on real physics. We're not here to listen to people expounding on their scifi or fantasy backgrounds (you could stick it on Purgatory, but a lot of people avoid that board anyway because they don't come here to chat). Just get straight to the point and say what the problem you're having is and what you want help with (like "I'm making a world with a glassy surface. How do I get that kind of effect in Celestia?" or something. We really don't need to know that it's an artificial skating rink world or that it's the detatched glass eye of a gigantic space octupus or whatever
).
Just keep going with it, keep busy, post the final results when they're done (not every step of the way), and just keep the fantasy backgrounds to the final zip files. You won't be guaranteed to get much in the way of feedback afterwards (but then nobody is, really), but at least you'll have finished it and you'll have undoubtedly learned something along the way about making textures and about how the real universe would work under those circumstances. And people may at least appreciate the effort that you've put into making your system, which sounds like it's going to be pretty large. And this is a good thing, right?
