Raven stamp WIP

Well this one has me slightly stumped and I hope you’ll tell me your thoughts!

* How, if at all, would you expect the wings to be delineated?

* Would there / should there be a gleam in its eye or a shimmery bit along its beak?

* It’s meant to be on a largish branch, but I think that’s a bit messed up. Any suggestions?

Thanks, everyone!
