Lots of updates!
your photoshop painting project: i must recommend that you put your lines as a multiply layer over a dark gray background. And then work your values and colors back in there. I tried it with my father christmas, and it really works great (for me at last). Anyway, don't work on a white background Also, i feel that the perspective on the background is more from above than the figure.
Last sketches: hey, do I see good paper? do you like it? Your lines are getting more under control. It might be good to try some more dynamic poses, they're hard but its really worth it...
