I really like it. The lighting could have been improved because I see on some parts light is emitting at a strong frequncy however where it should bounce off from or reflect doesn;t show. For example on the right side of the head should be a lot lighter (reflection) because of all that light coming from the top of the shoulder-blade. It's also too bright, reduce the lighting a bit because it's hard to see some of the detail there near his left waist.

And yes, this would have been nicer if it was up-scaled. On the up side, I love the colours and the flow. Also, I LOVE Frank Ocean <3 Good Job!
