Not really, i like they just look a bit unrealistic... Pichu and the gold Espeon's colours look good too... Charizard is okay, Gengar's colours look like they've been done with MSPaint...
The recolors look cool. I like the Gengar and Zangoose the best. What program do you use? It's cool to recolor because you can make new shinies of your own. You should do a red and green Porygon2 for Christmas, lol.
