The BG is just that a bg! Just happens to have a EVO on it, but that's an actual photo, not the chop! Hehe.
I like the ideas of the lines. But you might wanna redesign the ss so that it fits the fb a bit more. The holes and wings and such just feel somewhat random. They look cool and such individually, but but together they might conflict and make the chop a bit busy?
I think this will turn out great, cause you have a great donor there for brush and C&P
Keep at it!
Cheers!
