I really like your style, but I can't help but think this is slightly different. IT seems more set than your other work. Also, the style reminds me a lot of Scott Pilgrim by Brian Lee O'Malley. Her look reminds me a bit of Envy Adams in particular.
Awesome work! If you decide to do the rest of your work like this, I'd totally approve!
I love her boots
