I think you captured an obscenely unique mood by chopping half their head off, lol.
There's a weird balance in a "high horizon" drawing where the top and the bottom both have significant meaning, and I think you pulled this off excellently~! There's that stark contrast for the above part of the piece where it's a deep silhouette in front of a saturated night sky. Then the bottom half is all exclusively precision-based line art and smooth shading, dynamic shadows, and everything someone would come to expect and love from a character design~
A really nice perfected structure for a drawing, with a good choice of a serrated separation line ^^
