What types of file can cc3+ read? Do you mind if it is cartoony? Do you need it with the dagger in its claws? (That last one would be a real killer, I think. Google image search on "flying raven dagger" turned up one with a dagger, but the raven head is a skull and it is wearing a top hat.) If the files are suitable, I think a couple of the images here - http://clipart-library.com/raven-sil...-cliparts.html - would look good on a shield, though no daggers are included (and the page has several images that are clearly not ravens).
