Thank you for the feedback and for the questions!

1. I wanted to paint a half-transparent white thin clothes covering her shoulders, but with iridescent reflection. I haven't succeed well to paint that :D

2. Yes, I thought about some modeled dark leather protection around her hips, something that looks like two shells. Can also be pockets to hide things.

3. I thought about a common cloak, but with a sort of Scottish pattern on it , but smaller, and maybe not really Scottish too. But a pattern a bit orthogonal/squarely that mixes Cyan and Blue.I have to do research about it, the artwork only suggests its appearance without showing exactly what is it.

4. That's my mistake :) I think the ideal would be symmetrical, with leather gloves on both sides and a piece of tissue wrapping her forearm, hold by a thin leather belt. Something that can let the tissue float a bit. I'll have to draw more to figure out how it works. 

I'll try to add next week more drawings to this thread to detail that.
