I agree with the surp/mil pouches the green offsets your helmet. maybe if you dyed them black it would be a better fit. but i would remove the one on your back.
The skirt it a good idea, but what about a cape that draped from shoulder to shoulder.
I would also put your pants legs over the boots and get some spats or leg ties, and make the undersuit black as well. - i see your figure has that already- the gray color doesnt make your blue stand out a solid background will make everything look less spacey in between the armor gaps.
The cod piece is a great idea its sorta midieval, but why not come to a point with an armored half skirt that connects on the sides on the cod?
I would also make the shoulder bells bigger, maybe even one real bigger like your some sort of mando knight with maybe some blades coming off of it or whatnot. you have alot of stuff in the middle area and nothing up top so it would be more proportioned.
