First thing I noticed was that the sprites are pretty well made for a first scratch. The lines are nice and clean, they don't look shaky like some first time scratchers make their outlines.
Trup and Tint could be better shaded though. You used a technique called Pillow Shading. You don't wanna do that when you're not making Inferno or Inferno based pillow shades.
The shading could be a bit better, but I think that's just the style you were going for. Sprites in video games have different stlyes. These ones are small compared to Pokemon sprites, so they don't need that much shading.
So, yeah, they look pretty good for a first time.
if you need help with shading, I suggest
