Decided to judge the piece in person and just got the shipment a couple of minutes ago so I took some quick shots.
Armpit issue is there without even touching it in the box, there is very little room to try to stretch it up at all.
Despite not being able to have the armpits proper it isn't completely jarring.
Only other flaw I see is that there is a black spec of paint/dirt that I cant seem to be able to remove from the red superman symbol.
Overall seems like its a decent piece despite the armpits
