My rendition of Benedict Cumberbatch from Sherlock.

It's a really awesome show for those of you who haven't seen it. I highly reccommend checking it out!
Anyway, just some quick notes. Wow... that hair. I love curly hair, but it's always so hard to draw, it's the beautiful mistakes that makes curly hair look perfect in my opinion. The scarf and jacket were done in a loose cross-hatching technique. The face and skin I kept fairly smoothed over.
Also here's the original image I used:

I haven't watched the show yet myself, but I'm slowly being nudged closer and closer to doing so, haha.
You've painted him quite beautifully here, and the loose hatching is pretty expressive -- especially on the scarf. I also like how you've focused on the face and the eyes.
