"Angel on my Shoulder" little more progress

I didn't get much done because it is horribly hot right now. I'll try to work more on it tomorrow. I also have to remember to finish the hair. I almost forgot about the right side. I'm still unsure about the angle of the shirt and some of the shading on the chest, but the neck line is rather close to the reference. Though I do think I could bring it down a little on the left. Also I want to go back in and revisit the lips I think the bottom lip looks a little too outlined.
