Wow. This is quite an impressive piece. Your pencil work has always stood out to me but there's something about this that seems so much better than the rest. The dynamic feel, the emotion, the detail...

One thing I really like about this is how well drawn it is. The clothing shows great folds and the proportions on the face are well executed.

I do have one issue though. His right leg seems a bit awkward. I think it's too long. The suggested area of the thigh brings me to believe that the front of the leg should not go out as far as it is. The knee seems inhumanely stretched out. The calf is just fine but it seems a bit off when connected to the thigh like that. If you look at the left thigh it's just fine considering proportions and how it should be closer to us. Actually..the right leg should hit the ground a bit behind the left, considering its position.

That is just one mere detail to this whole piece. The speed lines are very nice, smooth, and believeable.

Great grayscale, some ares not filled completely, but I dont know if you were going for that or not.

I dont believe this piece needs a background, but it could become a whole new piece of its own with one, considering that this piece is currently a vignette with no background.

If you were to add a background I suggest pushing the character a bit off from the center. Give it some composition.

This piece has character, and I feel you are good at visually displaying that.

Keep up the good work.

I dont know but should something be going on near his back where the object is jutting out of his back?
