I don't really see anything in the above picture but I do see a difference in how the sleeve folds are painted. The original artist has painted the folds in a confident way on the arm to the right. But to me it appears that someone else has added a very weak and overdone set of folds on the sleeve to the left. Just where the elbow crook is. Is there something there or did the art directors ask for an add on? Who knows. In my opinion, it doesn't look good or right.
I zoomed in on the picture to where his right is raised. I think the arm and hand may have been higher and then it was lowered a little. There are some brush lines in the background just a bit higher and to the left that suggest that and that may be why the sleeves suffered a change in the folds.
I see what truthlover123 is talking about. Just above that arm is a part of the background that is a design. The background itself a loose abstract but in that area if you zoom in a bit, you see a "mirrored" image. Mirrored in that if divided it is equal on the left and right. That is different from the rest of the background abstract. Probably a joke by the WT artist knowing that people are looking for that kind of stuff.
I don't have photoshop on this comp or I would intensify the colors just to see what extent they played with the background.
