So I'm not hugely artistic, but I had fun participating in the CAP 4 deisgn process and I think I came up with some pretty not bad designs, so let me know what you think :3
Sorry if the lineart isn't as clean is it could be. I spent twenty minutes drawing and then erasing everything while marathoning Glad You Came by The Wanted D:
My prevo's follow the standard metamorphosis line, but I tried to add some different things. Mainly, in the LC form, Aurumoth's ominous helmet is actually little more than a mask, which can even be removed. My thought process was that baby Aurumoths make the masks themselves and wear them in order to be more like their full-grown selves (a-la Happiny and her egg stand-in), but the idea of a caterpillar with no arms crafting such an intricate mask is a little hard to swallow. Also, ignore the sketch-note that says "covered in fur." Originally it was, but I changed it to just having a puffy chest.
For Aurumoth's NVE form, I went with the idea Koa stated in that Aurumoth's wings are actually the shell of it's former evolution, although it's a bit more blatant here. In this form, the LC's mask has become more of a helmet (although if you look closely, you can see it doesn't cover his whole head). I also toyed with the idea of Aurumoth's upper wings being initially part of his helmet, and they detach and float above him at some point in evolution. BTW, if you noticed my sketch-note that says "upside-down," my original idea with the NFE was that he hung upside-down from trees for the majority of this stage in his life, although I actually rather prefer the idea of him floating around better.
COMMENTS FROM SOMEONE WITH DEMONSTRABLY MINIMAL ARTISTIC KNOWLEDGE:
Kadew: Nothing that hasn't already been said before; you're LC is adorable and you NFE is very well done. I especially like how you did his puffy chest beneath his armor; I don't know how to describe it, but he looks like he's wearing clothes of some kind, so that's adorable/badass all at once. I'm not sold on the idea of having two different specialized shells for offense and defense, since I feel like it's kind of pointless asymmetry, but I'll let you be the judge.
Quanyails: I much prefer your new LC to your old one, as I'm pretty sure everyone does, and I really like the knight theme going on with your NFE. Not much else I feel I can say about it; keep it up and show us some more of your NFE sometime :D
Eol: I love how you approached the bug concept from something other than a caterpillar, which has been a pretty popular idea so far. Making the primary focus of his design the light is also pretty cool. I much prefer his blue design to his white one, but I found that it makes him look hauntingly creepy with his eyes open. That's not a bad thing, mind; I just want to make sure it's something you intended with your design. Cute-but-creepy Pokemon are always winners to me.
The Steam Punk: Your LC is adorable, and the notion of him suspending himself from tress with silk to imitate levitating is very creative and well done. I'm not quite as sold on your NFE though; you incorporated the psychic flavor nicely by having him walk around on his levitating shells, but using those shapes as legs just doesn't feel natural to me.
Koa: The new eyes look much better :3 As far as design goes, I'm not sure if I care for either of your LC's just yet. The baby bug just seems kind of bland and the caterpillar still seems kind of awkward in that stance. I feel like the perfect LC is resting somewhere between those two points, however. Maybe if I could see your LC in different positions other than "reared-up," I could form a better opinion. I do like the fact that you didn't make your prevo "cute," though. He looks like something alien, and I think that works pretty well with Aurumoth's mysterious nature.
CBMeadow: I feel like I've said this a hundred times by now, but you LC is also very adorable. Kudos for not doing a metamorphosis line, by the way. I think your NFE lacks a bit of personality though, if that makes any sense. I get he's supposed to be a volatile wasp that learns to chill the fuck out when it evolves, but his design really doesn't go much farther past "Aurumoth, but angrier and silver." He looks too much like Aurumoth is what I think I'm trying to say here.
