Hi Erza! I haven't seen or read any Naruto so I don't know how much help I'll be x)
Your coloring and shading is great as always! I'm surprised at how bright everything was, even before you edited
You seem to need a lot less editing than I do, which is a good thing lol. I'm wondering why you decided to edit out the lines on his cheeks, though. From what I've seen, those marks are a pretty important character design. With Naruto art, the most recognizable features are his hair, headband, and cheek markings are what makes him stand out the most.
Besides that comment I really have no issues with this Great job! I'm glad you're starting to edit on Gimp. For me, once you get the hang of it, it can be a great tool!

As a former (and rather excellent) liar herself, Aru knew that, sometimes, speaking the truth felt like wrenching a thorn out of your side. But doing the opposite meant pretending it wasn't there. And that made every single step ache. It was no way to live. — Roshani Chokshi, Aru Shah and the Nectar of Immortality
