Extremely cute Eevee!

So cute I could DIE! Seriously,very good.

Fair warning, I absolutely adore eevees! So I might be a bit bias.

The way you have drawn eevee is very interesting! I adore how the background makes it stand out, not to mention compliments the eye color! Plus, your lines and shading are very well done! I especially love the tuft of fur on it's forehead and chest, it makes eevee look fluffy and adorable! The only thing that I can really see off, is perhaps the chest tuft's size compared to the small body. I personally think it makes it look even cuter, but I'm just trying to point out that it sort of makes the body seem a bit mis-proportioned. It might just be the way that the eevee is facing, which is why it's a very minor thing to notice.

Overall, this artwork is outstanding! Good job and keep up the great work! :D
