It's really bland because of all the brushing. Looks like it took 5 mins. <-that's a bad thing. It has no depth to it either. I would take more time and try some different kind of effects instead of just brushing, unless you did other stuff than brush.... then idk.
lol i didnt brush at all i added c4ds and blended them hard to see and i wanted to s ig to fit him but o well /failed
