Graphite girl.

I hope everyone had a wonderful Christmas. Ours was sooo good. We had family, food, love and fun. It was truly the best. 

This girl is all graphite on 140lbs. hot pressed paper. I've started coloring her since I took this photo and I'm not so happy. It seems that I always ruin a drawing when I add color. I"m not sure what's up with that. Here she is so far:

Does anyone have any advice or suggestions? She just doesn't have any pop, ya know?
