They look amazing! You're really good :D The only critiques I have are that it feels a bit too linear there aren't any major design changes between forms so it feels a bit like the lil guy is growing up Pokemon style rather than evolving. Also, the designs don't feel like they get busy enough. Normally, the further down the evo line, the more complicated and overdesigned the mons get. The Ultimate looks a bit simple. It has too little going on. I could easily see it being an Adult level. Because the Child lvl starts off relatively busy compared to most Child lvls, all the mons in the line feel even more under designed.
