Building off of Eyecraft's edit, if thats ok. I really like the peice, looks a bit statuesque, with the copper like skin, was that intended?
Anyways, 2 things I noticed:
1. Left side looks rather unfinished, the lower part of box one is without outline, I suggest you touch it up.
Also The border has the same issue as box number 2 (which I didn't really resolve that well.)
2. The border is perfectly flat, based on your creases above it, I'm assuming this is a looser material, Therefore the border should not be exempt from creases, so I shaded it appropriately.
Also, I noticed the blocky AA on the right border going inward and the difference in pant leg thickness, which would imply a uneven posture or some other bias, but I did not have time to edit it, I'm sure you get what I mean though.
Hope this helps!
