Hello again, long time no see- but I see some great improvements in your sketchbook.
Those hand studies are bloody brilliant, and I liked the sculptures.
Try to neaten the linework on your other things, it looks like you took loads of care and time into the hands, why not translate that new found understanding of form onto your figures/faces now?
Anyways, you're a hard worker and already it's reaping benefits. Just keep at it.
