As much as I like how Chris Bulked up for the role perfectly, I still have a little concern about something very intricate on the character.  Why it seems that Chris have a brown hair here?   If I recall, Steve Rogers sports a blonde hair and definitely never becomes a brunette on any story arc.  I know this is just a minor detail, but the hair color is a very important element on Steve Rogers' character.

Still hoping they can fix this.
