Just unboxed this about 45 mins ago.
First impression: the body is average at best, and that's being generous. The sculpt though, however, is excellent. I personally think it's the best sculpt of the GotG line, but the subpar body makes it the weakest figure overall of the line.
Depending on the pose and the angle though, this figure can look good. It really comes down to getting the correct angle with this figure and obfuscating the lacking areas of the body. The best angle for this figure is indeed seemingly posing him at an angle, as when doing so, it actually looks pretty decent. It's only when you have it looking straight on or flare the arms too far out to the side, that it starts looking a little peculiar.
I would not get this figure as a stand alone figure by itself and if you look at him by himself, that's when the flaws are more discernible; but if you have the rest of the GotG group (or at least most of them) though, he's pretty much essential and looks fine when displayed with the others. As mentioned, just pose him at the right angle and he'll be okay. Even with the body as is, he still looks more massive than the other GotG figures (excluding Groot).
