I get the idea, but the thing is, it looks way to "big". Using rhino as its comparison model shows just how big on the shoulders it is. If you used it on someone like Excalibur, it would expand past their shoulders, and a frame like Valkyr would literally be engulfed in this syandana. It is FAR to large for my taste personally, and I feel like other people would feel similarly.

I'd say just shorten the length of the shoulder area and maybe decide more on a decending or ascending length increase. Right now it's far to square, and everything looks just flat and fat.

I hope this helps, it's great modeling none the less, you did a good job outside of the size and shape.
