oh man, those old revamps and chao sprites bring back a lot of memories. at one point i was so infatuated with the idea of chao + pokemon, i actually tried to make an rpg based around them..tibia honest. heheh.

i like your pixel overs, but i feel like the charizard is still pretty unfinished. maybe...add a little more shading to give it some more depth? your contrast is also a little low with the black and dark blue shades. why not work on this some more when you get time, maybe make it more like your gardevoir there? i know you, and i've seen your revamps: you've got so much unused potential here! make the most out of it.

i'm also really lovin' that reposed umbreon, too. what was the original sprite / pokemon? re-posing is a great way to work on making things "from scratch," in my honest opinion.

can't wait to at least see a few more revamps. keep it up, kid, you're doing great.
