Wow, sounds like you have a lot going! I would like to check out your works sometime.
RWBY is awesome. Have you tried the game on Steam?
Since you have been focusing on Gundam, ever considered modding/kitbashing your suits for real?
I did some in Gundam Breaker 3, and it's really fun (and quite the relief) to be able to build my own suits.
They don't have everything, and it's not real Gunpla, but sure saves you a bit on the $ side, and you can quickly
concept things out.
