I really love the drawing. I must say it also reminds me of my favorite class from Diablo II: Throne of Bhaal, the...assassin... suddenly I feel like that may well have been intentional on your part. Also makes me think of one of the characters in the current D&D party I'm in.
This is a very well done piece. The thought put into her costume is very clear in that it is somewhat showy but in a somewhat cloistered fashion such as the body armour that, while it protrudes somewhat it does not reach past the shoulders thus restricting movement. The same going for most of the suit in that it is all pressed tightly against her body which matches her motif as an assassin. The carapace style of the armour gives her an Asiatic look accentuated by the hair ties, making me reminiscent of the fire nation from Avatar the Last Airbender with the red and black colouring.
She has a very thin appearance. Not starved but trim and not overtly muscular. That look matches her weapons well, the fist blade and dagger both seeming more extensions of herself rather than held weapons. Wonderful work on the pattern for her stocking, the extra effort in the design giving her an exotic and sexy look and adding to her figure as a whole. I am very impressed by the anatomy of her and the way everything is in such precise proportion, particularly the finger work. Most excellent. I like the pattern on the cloth in front of her groin with those tassels near the bottom. A curious aesthetic choice but it adds to the piece very well. Her expression is well done, the focused and determined look matching her well.
Her surroundings are magnificently done. The glow from a lantern illuminating her giving her a very dangerous and deadly appearance, particularly with the background lit by the moonlight. The cracks in the wall are very natural looking, as is the cobble stone street. The little details like the small pile of rubble from the wall near her feet give the alleyway a dilapidated feel that plays wonderfully on the theme of stalking someone in the night to murder them, you are very skilled at setting a scene.
Magnificent peace. They say a picture says a thousand words and you have written a short story with this one.
