the first one: your drawing ability, is of coarse, great, but ya, your right. thereis something about it, just looking at it, that gives me an uneasy feeling about it. A wierd angle maybe?
The second one is soo cute. I absolutely love your cartoony style!! "eeeee" screams like fangirl
The 3rd. interesting scene your setting up there. It's intersting how the woman is all curvy, organic lines, and really stands out from all the geometric shapes and hard lines. When you start to add detail to the background, and color it in…...well I know it will be so awsome. (and ya, it looks like califa [sp]) :P
