Not really sure if You'd call them "goth" but here are a few i made awhile ago.. maybe give you an idea to go a bit more "jagged" ?
With arrowhead in his tummy:
With wings pointed up
or maybe go with 'boney' wings?
or ones that look sorta 'tribal'?
I would make his hooves a bit more aggressive, maybe smooth out the wings a little
If you go with the 'skull"motif, you gotta make his head more aggressive!
