I do love the hair swish

The rust is really nice. Have you thought of using darker varients of the colors used in this image for the outline? I'd live to see how that would look.

I really like this. My only complaint is the brighter color in the background makes it harder to see his hair. Try using a color that makes the whole thing pop out.

Not bad, I'd suggest not having the colors in the sky wrapping arounf the tomb stone or the crow, it kind of gives it a halo look. If you instead make the colors straight, it will give it a more natural look

One thing I have always enjoyed doing was using darker varients of a color as part of an outline. I bet this would look alot nicer without the black outlines.

I really love how you limited the space and still made it look like a car. Very nice! :)
