One problem right off the bat I spot with Bengal, is that her hair is practically neon-yellow. Doesn't look well. Tone the color down, desaturate it slightly, shift along the hues as you get darker or lighter. It'll help a lot in the future.
Also, since I assume you were going for a Pokemon style, she's missing several black outlines to "punch out" her figure a bit more, in keeping with the style's standards.
Cascade is alright, although I'm worried about the length of her hair (She could trip. =P), and her shirt seems to make her look unusually fat, as do her legs, which doesn't seem to be the case with her arms.
Also, for Crawleep, you should position it's standing hand somewhere closer to it's center. It looks a bit off balance and it could be bad for the Pokemon that way. Otherwise, good work.
[this is not a flame reply xD]
I forgot to add Cascade was supposed to be an edit of me- because my hair is long, but I decided to leave out a few details
And as you can tell, I did BEngal in a few secodns for an RP xD lol
And for Crawleep, IDK what your talking 'bout but I'll try =3
