A character from Bakemonogatari/Nisemonogatari
I really like those animes, and I love the art style in them.
This took around 12 hours.
It was a real pain in the butt to shade large portions with 3b, 5b, and 6b pencils. The texture of the paper shows through. This is why I stay away from characters with dark hair. It would have been easier if more was going on with her hair. There's large patches with no variation in darkness.
That said, I really enjoyed shading her face, and did fairly well on her hand.
