A nice sketch and design
wow what a mixture here love it, and it being a drawing in black and white was intense, I would suggest as a small form of improvment adding a border along the edges would be a nice touch, This one here is awsome I love how raw the detail is with these black and white ones, I like the detail that just has a vibrant look and "THE-VIEW-POINTS-ARE-BEAUTIFULL" so nice design here, anyways nice work here and "I-LOOK-FORWARD-TO-MORE" of these designs and your future works.
