Seriously, your revamps look exquisite though some of the sprites especially the trainer sprites don't look that much of a human because of that size limitation :\
Let me point out some things that bug me:
-Gastly's gas doesn't look like gas but more of an ooze, maybe a little dithering could fix this
-Slowpoke on my opinion is based from the D/P/Pt sprite, no?
-Snorlax definitely needs some adjustments on its back, it looks like its suffocating :P
-Blue, Bruno and Red lacks anatomy. . . Blue and Red's heads, and limbs don't fit their bodies, and Bruno's head looks like it's copy-pasted
