First Digital Portrait - Katie Ermilio

This is my first try drawing a portrait using Sai Paint Tool.
I have always had trouble using colors for skin. Skin is the #1 problem for me to draw, second is hands and third is dresses. Took me at least 6-8 hours? I do not know, I didn't count.

I have looked over a lot of tutorials but helped me the most.

Remember, this is my first time. No hate =.=
