Have you ever tried doing negatives? Starting up with a black page and creating the image by shaping the white? I feel like it would work really well with your style.

Well normally you should work on a black surface and draw the places we're there's light. In a normal drawing like you did, you start with everything at maximum luminosity and slowly draw the shadows. In negative drawing, imagine that the character is in a pitch dark room with a few light sources. Only parts of the character are shown and borderlines are rare.
The idea is that your existing shadows and the background become one. Giving a different atmosphere to your drawing. Good for gloomy, dark, strange emotions.
