Help! Art beta/advice wanted!

So.
I'm trying to do a dragon Sam and Dean picture and I'm stuck. Can anyone help kick me out of this rut? Here's as far as I've got.


I want to do scales and shit, and I want to sort out Dean's colour because that green just isn't right, and I have no idea what to do with the wings. If you need to see it bigger click though to imgr to magnify it.

Ignore the random red, that's just an underlay, not blood. Yet.

Any advice?
