They look nice, can I ask what you did to create it? I don't mean detail I just have the weird impression that you used a c4d and the lead singers body then used some erasing tool. If that's the case though I think it is bad. Other wise I like it. Maybe a text and border would be nice for add-ons though it seems kind of empty.
You think it's bad if it's simple? Bloody hell... You judge something on how it's made...the final outcome, who cares how simple or complicated it is?
