on the left? lol you mean right. and actually it supposed to be obvious it signifies his arm is in motion by its shape.
Would it be better if the person is colored or if the c4d was desaturated like the person? Anyways, Nice job to both of you. Great text too.
erm.. no? Maybe it's not a c4d render, but whatever "it" is, I think it seems out of place: I like the one on the right.
