Great SB. Cool to see you do both tonal / color and line studies. Color and tone are two things my own sketchbook is sorely lacking right now. You've done allot of cool figure studies, maybe mix it up a bit and create piece with multiple figures, a background and a higher level of finish? Would be very interesting to see.
Also maybe start combining the human form with some animal / insect shapes and get that imagination running with some freaky concepts?
I really like the gestures from post 80 since you've left the lines more open there. You tend to close the lines in most of your studies and this is not always a good thing (advice that was recently given to me too, as I do the same thing ).
Check out some work by Henry Yan or Rebecca Kimmel to see awesome figure drawing. They also leave major open spots in some of their works and it looks great. Leaves something for the mind of the viewer to fill in.
Very cool sketchbook. Keep drawing from life and keep the updates coming!
Level up study. Darn it edge control and over all managing the hards and softs is bloody difficult and at this stage slow for me. I think I'm doing it wrong in some way. I Feel like My stokes don't have enough control to them and that They destroy the suff underneath them instead of building on top of the old. Practice practice practice.
-> I can see that everything is a bit off. I don't know exactly how to fix it. I added shortcut commands to Flip horizontally and flip vertically in photoshop and I've been using them a lot. It helps spotting the areas with mistakes. -> now to figure how to make them right, somehow.. -> Challenge accepted >:3
