Not bad. The shading is pretty good, and I like the highlights in the Eevee girl's hair. ^__^
Eevee girl's neck is a little too thick. Girls' neck's usually aren't too thick. And at the angle Aiden's standing, you should be able to see his other shoulder and arm.
Hope that helps! Your doing great.
Yay! Another piccy! Summer looks okay, except that her right eye seems to be a little off. Shading is perfect! Her chest resembles Nami's. Kudos to ya! ^_^
