OK, CnC time!
The Wartortle cosplayer is good, the parts are attached well, the ears look great, this is my favorite.
The Charizard cosplayer looks good but the wings look a little odd to me, maybe it's just the proportion.
The dragonite recolour is recoloured well but it looks kinda wierd. But I think it's only because its a HGSS sprite and Mewtwo sprites.
I like that Gallade fusion. It recoloured very nicely and the parts flow incredibly well. Honestly, If someone didn't know about Pokemon, I bet they would think this is an official sprite.
The Palkia and Dialga colour-swap is nice and original. Not really much to say. My favorite is the Dialga colored Palkia.
