Very cool drawing, man. I love the contrast and overall randomness of the content and how in spite of it being random it all feels cohesive because balance of dark and light on the drawing itself.
However, what brings this down is the framing of the piece. you have way too much blank space on the top and bottom which messes up what would be a strong composition. Also get that pen out of there, its super black and draws a lot of attention to itself as opposed to the drawing. Great job though and a simple cropping can easily fix all of the issues I personally have with this drawing, but presented as it is currently brings it down.
