Love the style
The outter border piece could be a bit darker or even in some color shade or something, So I have always loved this black and white style but you bring a certain flavor to it making it more then just black and white drawing its talent with ink and pen or paint lol anyways great sketch design here its filled with ideas and imagination, I have really enjoyed this.
