No No No, our Momo looks really impressive, His ARMS (All the components) look impressive and vascular giving us a flashback of Ronnie Coleman arms, I think than with more brachialis and triceps he can easily match the best arms nowadays: Phil Heath.
I like the look too, but his back is way to small and yes he is not thick enough even his legs(hams) in the side chest pose. I think what it is, is his quads and arms over power the rest of him so it makes him look a little weird.
His arms are very good, but he needs more overall thickness if he's going to make an impact on such a strong lineup. Hopefully he will bring an awsome conditioning and he seems to be on track in that department.
