I can see what you mean brad,.....bt it's all sortof forced perspective,.....his left hand if nothing else should be even bigger because it's coming toward you,...and since the angle is a sloping downward shot,......his whole body would get smaller and smaller,.....
just my thought on it,.....
i'm sure the tattoo artist will make any abrupt changes that are needed,...
pluswrapping a design around an arm / leg etc.
would mean certain things askew anyway ,...and would have to compensated ,...
sorry if thats confusing,....i get that look all day at the tattoo shop when i try to explain why something flat looks flat,....
and why 3d is the way to go ,....hahahah
