I suggest you better take off the Psychic train OW, since it wasn't yours or Nintendo's in the first place, it was Avatar's.
1- The Ghostly OW's are Photoshopped or GIMP'd, all you did was ink over them. It's obvious since the sprites aren't all the same shades. So I don't exactly have anything to say.
2- Chimchar is the exact same as 1.
3- The Mothim isn't very over shaded, since all you did is dither with the normal pallete. Try adding more colors for over shades.
4- Ampharos is pretty good. Nothing bad to say, except the tail looks more like a diamond than sphere.
5- Nothing much to say about the TCG OW, except it looks like a recolor more than a revamp.
