I feel the same whenever I saw a custom run of the suit with it stitched on. The edge always looks too thick.
It needs to be done so that the edge is just
barely visible. I've only ever seen it done properly on bigger scale statues since they have more room to play with at that scale with it being sculpted. Just don't think it's possible in 1/6 but I'd love to be proven wrong. The edge of the symbol shouldn't be distracting my eyes away from the rest of it.
Problem is, I don't think slapping a ****** sticker on his chest is the way to go about it either. It's a tough one to crack.
