thats a good texture idea, I always liked that style outfit in ac after they fixed the hunch back issue...possible improvements for your texture would be more quilting on leg areas, the buttons are double in hip area, more plating in chest area, larger texture on the sleeve area..have you tried simply drawing the shoulderpad area in?...it may work out ok...draw the shadows in to make them look like they are actually seperate section...thats all they did on the model texture in ac...not a seperate peice...looks like you're doing a great job :)
