I like them! My favorite's the Eevee girl one. I like the thinner outline rather than the thick one in the other picture. I used to do really thick outlines, but then I got used to the thinner ones and my computer art looks much better. So, I suggest trying to keep with the thin lines.
Your style reminds me a lot of my brother's (it's a compliment ^^), the way you draw eyes and faces and such just looks a lot like the way he does.
