I must agree! You really really are getting the hang of shading appropriately.. It's not too dark or too light where it shouldn't be. Good picture overall, too. My next critiscism: Nice control of the pen. You're very good at shading in one direction. Next, maybe you can try cross-hatching (overlapping lines in different directions) on your next sketch. It'll make things look a little smoother if done right, but it takes quite a bit of control to do it right consistently.

yha i haven't learned any crosshatching yet, ive just been kinda winging it while i have free school time.
