I love this. I absolutely love it. The movement in the lines are fantastic. The contrasting colors. Ugh, just beautiful. The only thing I would have done is add a bit more color around the neck. I see where you added some. I'd add more at the start of the neck, where you made shading/pen marks. Maybe would have added lines that drips from both of the the shoulder lines.(Just something I've noticed from studying and observing styles similar to this.) But do know I love this, and I'm definitely following you.
