Wow! you must really know what you're doing and drawing in terms of how greater a job on how you render your lines and figures, Jcml fine art, but I'm not totally getting enough of your bolder and even more bolder posing and exaggeration in your shapes and lines, so would you like to go for 2.5 more hours of 30 second even more quicker scribbles like you're Kandinsky and Pollack? As a result, if you do these stuffs as you're listening to your music, you'll be able to help yourself relax and be even more nicer to yourself and enjoy even more with your drawing process. If you're curious about even more gesture sketching for comics, cartooning, and animation, I suggest you look at this video down here.
