hehe, blend your render in some more ^_^ all in all it's not bad for two weeks of experience. Just look at some tutorials or at other ppl's sig and u'll be ok.
not bad not bad jus maybe try bledning him in a lil with the backgorund,try adding some graident maps etc if u can.
I think it's quite good. For two weeks, very good. I would just darken the flames a little bit and blend the front pic.
