I can understand why you would think that, but this is frame 17 of a 22 frame animation. In the animation the bird turns it head to it's left (our right) which is why the Raven is off-center. 

I haven't gotten even close to finishing all the frames, and I needed a change-of-pace so it's on the back burner. Until then I wanted a decent avatar so I uploaded this. 

This is the preanimation version.

I really do wish that this raven was was finished with both wings. There's enough space to do this and I feel that the cut off really lets down a very nice picture.

By popular demand the white line has been removed. 
 

I agree with Eliot and Victor.

I´m with eliotfellow. the eye and the palette is great.

 I like the raven, but I'm not so sure about the L-shaped border? I think it could be borderless and still be good.
