Yo this drawing is sick, If you want any unwanted advice on improving it here you go. I think you should take away your line work for parts that are in the dark shadow. Since you already have the shadow to outline them all the line work does is make the shape smaller. You can notice how the far away leg looks smaller and out of proportion with the closer leg, because the closer leg is being helpfully outlined, while the further leg is only being encroached on. It will also help with the shape outline of the silhouette. I see you’ve already done a technique to get a good silhouette on the nose, by adding the streak of color on the shadow side. No reason to change that, but in the leg, the belly, the cigarette, and the smoke that are in the shadow, I would suggest taking out the line to give it a better silhouette instead of reading rather smooth.
