Was going to write something about this earlier lol, but yeah it's looking good and very clean and like i've said alot of times you've improved quite a lot buddy.
Can I just say that the bits I can see that are looking abit off would be the whole squareness of the shading - Top left of his head, and to the side of his hat ( bottom right ) But apart from that it's getting good, now all you need to do is add depth to your work with more colours etc. But i've seen alot of web-comics start off with this standard and have grown to look visually amazing.
Good luck and I hope to see more ^^, P.S: More Naruto characters woop.
