Yeah, I agree with you that this is probably the best Naruto fan art you've done in a while. I think you're just starting to get pretty good at manga colorings, but your fan art honestly needs more work. Now i'm not sure how good of you are at free hand drawing away from the computer, but i'd imagine useing a mouse must be more difficult. Anyways, I noticed that you're useing shadows better, and more often, which is definetly a good thing. It also seems that Naruto's body parts are more in proportion than last time as well. So I do think you're making a liitle bit of progress. Of course there is still plenty of room for improvements in all skill categories. Well anyways, I think if you started to make your fan arts more detailed it would improve them a lot. For instance, there seems to be a wall behind Naruto, because there's a poster behind him. If I were you I would of tried to finish, and complete the wall behind him. That way it would clearly appear that theres a floor beneath him, and a wall behind him. Well, I think that's the best advice I can give you right now. Just keep on practicing, and like Naruto never give up. Just remember everyone has a different pace of progression, so be patient with yourself.
