Beautiful work! I love the purple spot colour for the iris. Most people only do blue or silver eyes, if at all. The plain green background helps to focus the eye on the character, whilst having the hair flowing over to the right helps to keep it original yet keep it distinctly 2B. In addition the lighting is done extremely well and you have kept the shadows in the right places but, at the same time, not have them overpower the artwork, as i have sometimes seen. All in all one, of my favourite 2B artworks yet. Keep up the good work!
