Did you have to do the scales from the bottom to the top then? That's the only logical way I can think that it'd be done that'd be easiest. Then put the collar over it right? hmm.... This is very well done, Cap looks a little sad though. Like he's just had the epiphany that the fighting will never stop but who else is going to do the job?
Outstanding! Hope you post photos from other angles. Great design, pose, composition, expression . . . . you should sell an edition, I bet they'd go fast.
