25min figure sketch

Done as part of a 1 hour class. Didn't have any time left over like I do sometimes on longer sketches, so I guess I paced myself well, or it was because there are two figures ha. I'm not happy with my faces - I just wanted to put in a hint of features, and yeah... I feel like I'm making good progress with my contour lines but not so much with capturing the light and shadows. My lines are very sketchy, trying to work on that as well. My current goal is: Improve at correctly capturing the overall proportions of the human form, as well as rendering light and shadows. Thanks for any comments and suggestions!
