hanz0 showed me a great way to texture cloth, and since the helmet and cape are already done I'll probably just cut out some parts and put them back on the .psd.
Also, I'd like to state that the stroke on the cape isn't a stroke at all, it's a border. Once I add cloth texturing and embroidering/designs, it'll be sort of clear. I may end up throwing out the cape altogether in favor of full ceremonial armor.
