ok couple of things: first, the skulls! it has been done already. everything is skulls. but this is still pretty okay in the sea of skulls! needs to be a bit bigger and now it’s more like a sketch than a final project. maybe work on some colours and maybe fill the skull with something. and this might work very good if you play around with the colors! I mean, use some weird fcked up color combinations. like purple and yellow and teal and things like that. also, I think this would be a bad-ass tattoo. take this to your local tattoo shop and sell it as a “flash card” to them. a flash card is like a ready made tattoo for someone with no idea what to tattoo etc. :) keep up the good work!
