When I saw that fire, I thought to myself, "Yep, that's definitely influenced by his tattoo background." That's not a bad thing, and it's not like I know a lot about tattoo fire styles, but it's what popped into my head.
As for the nose, I actually have a weakness for noses rendered like that. In my sketchbook there's a lot of characters with pasted on triangle looking noses like yours.
Sorry, just wandering through, don't mind me. I shall go now.
