I also wanted to make the no capes joke, but Kelheor got there first !
But, on a serious note - if you want blue to be the main color, then definitely no cape. Since blue and orange are contrasting colors, and they're so saturated, the orange cape draws the eye away from the main acting areas (face/eye, hands) of the character. It kinda makes me stare at the crotch, which I don't think is intended
I think those small accents of orange carry just fine without the cape. The palette overall is strong, though !
