I like your drawing and I think your gesture is pretty nice.I noticed that your drawing is from the pencil tip most, which I guess you using the wrist more to finish your drawing. Try to practice using elbow and shoulder, it might improve your line quality.
Thanks for your tips! These are digital, actually. Hence, why the lines are thinner. I should probably turn up the maximum size to add more variation, though. It'll help me focus more on the bigger shapes early on.
these are really good your gestures are amazing!!! i see in day 2 youve started to put more detail into lighting so i think continuing to build shadows + highlights will really bring your pieces to life :) remember not to be afraid put darker shadows, try to mimic the tones you see in the reference
