If you're looking for critique... allow me to help!
Coming from a person who has yet to watch any of the Marvel movies (I know, I know. I'll get to it. My boyfriend and I love the stuff I'm just slow. xD) I think it looks amazing! The only thing I see off about it is the jagged shift of the gold trim on the front of the shirt. It looks like it suddenly shifts over by 2 pixels instead of having a smooth one shift followed by another shift of one pixel. It makes the 'flaring out' of the front look neater and more elegant that way.
Then again my eyes could just be playing tricks on me. Shades of red do that sometimes when next to bright colors. @_@ And yet I'm NOT colorblind...
I just wanted to thank you both for your feedback! I'll keep it in mind the next time that I design a pattern.
(Unfortunately, I can't edit or update this one - All I've got left are the QR codes, because the save file I designed it on was corrupted and had to be deleted.)
