A nice Black and white sketch
Wow this was just amazing work here I love the black and white but love the sharp detail even more, I would suggest adding some frame work on this, You have a great eye for detail and your talent makes the visual come alive, its stuff like this that allows me to enjoy these, Its "THE-SMALL-DETAILS" that bring this all together and you have showcased some "BEAUTIFUL-BLACK-N-WHITE", and these types can go a long way.
