Thanks alot, yeah i will continue to practice anatomy, i don't practice much though, in fact, this drawing in itself was practice... I'm not very creative with scenery and stances/poses etc either, i'm pretty terrible at thinking of good stuff actually..!
About her expression and the rope... I just made her face for fun, like i said, for practice... I had no finished image in my head, so it was just an on-the-go drawing, and the stuff i practiced was authentic eyes, nose, the mouth (and not just a smile, i do that too much, so here's a change) and later while i was at it, the glose and how it reflects light...
At first she wasn't even supposed to have her hand showing, but it looked so bland and empty, so i put her hand there... Then i thought i'd try putting the rope there too for no particular reason... Used no reference either, and that's showing, since i forgot certain things, like how the middle piece armor/uniform thingy btween her breasts looked like, i later checked and realized there's no plating at all, haha..
