Looking for constructive criticism

Well its still a wip...I think this piece is a bit too dark. I'm trying to go for all the color concentrating in the center of the piece. But then again I felt like it's too busy and idk kinda annoying (?)

Haha im yapping...I need another sets of eyes

TLDR; How do I make this more eye appealing? And do you see any mistake please tell me, I can't see it anymore
