Drawing a female with curly hair

Hello everyone on hive this is a drawing of a girl with curly hair. I got the image from www.istockphotos.com. drawing a curly hair is really hard but I tried my best to get the curls and the lighting, and it was somewhat okay,

​

I used grid line to draw just for accuracy, I sketched out drawing,then l started from the hair which was the hardest part, I was shading the hair square by square until I finished It. I spent close to 5 hours on the hair.

Then I shaded and blended the face and it features.

Then I shaded and blended the the the skin, and then I had my final result.

Thanks for viewing my post have a wonderful day
