Wow
I love this piece and to me this is a "BLACK-AND-WHITE" piece here but its charcoal and it really looked awsome the design alone is pretty good and to come out with charcoal is pretty nice so nice detail here, I think as an idea I might suggest adding some slight borders on this piece, anyways keep up the amazing work.
