RPG Monster sprites

[Neslug]

While the designs themselves are good, you might want to try smoothening the outlines in a few of them. Also, the shading makes it look like the lightsource is inconsistent at parts (such as Gulpasaur's upper lip having the lighter colour on the underside, while the lower lip has it on the top). Colours could be a bit paler, too, such as on the slime.
