Hey! Greetings from a fellow Utahn! BTW, there is also cheap figure drawing at the U of U on Saturday mornings.
Your drawings are beautiful and the use of the medium is lovely. As far as pushing it goes, I have only one suggestion. Instead of leaving the figures floating in the middle of the page, in which case they are well-drawn but poorly composed, I'd try pushing to the edges of the canvas. Put the figure in space. Break the edges. Instead of fading the legs out, as you do in the second (busty) drawing, draw to the edge. Start in a corner instead of in the middle of the page. It's understandable that we put figure drawing in the middle of the page ... most of the time we're doing studies of anatomy and light and medium, etc. But I think it can be interesting if we don't ignore composition.
Great stuff! Keep it coming.
