Look at Cellebis arms, now look at her legs. Way out of proportion! Plus she doesn't have toes, and yet she has fingers?
That's a little too realistic, lol. That looks like some sort of dinosaur (I know Tyranitar was supposed to be dinosaur-like... but not that much, lol)
If I redesigned one then I'd say Unown. The concept is not bad... except that the fact that each one corresponds to a letter of the English alphabet is odd, seeing as they're ancient and English didn't exist back then. So they could go with the Latin alphabet and remove the "J" and the "U" and some others... or they could be designed to be completely different (maybe like heiroglyphs or something).
Also, I'd like to redesign Mew and Mewtwo so that their colours match the original colours. Mew was supposed to be white with a slight pink tint and Mewtwo was supposed to be white with a slight purple tint... but now they've gone and made it so extreme that Mew literaly is pink and Mewtwo literally is purple. I remember seeing the poster for the movie and thinking "why are they coloured that way on the poster?" (and I didn't like it at all). And now it's as if the colouring on the poster is the official colouring or something.
Venusaur(awful compared to BULBASAUR!!!),Emboar,Typhlosion(so simple),Dragonite(so awful sprite-like compared to Salamence),Machamp(-2 hands),Conkeldurr(like venusaur)and much much more....
also pupitar and shlegon changed to something like fraxure would be better
Patrat, those eyes give me nightmares
I hear it's never too late if you really stick to the program!
