Well on the trainers, you just actually cut other trainers heads and pasted them on the other bodies. Next time, try someting original. The only sprite I would consider decent is the Zangoose sprite. But on the dark side of it get rid of the white dots. I like the mix too just too much black. The revemps are not revemaps, they're recolors. Try to add custom shadeing on it. Not even going to comment much on those. Atleast get rid of the backoutlines.
