The hat looks fun. I like seeing these smaller works from you.
I may have asked this before, but have you considered drawing fantasy elements on live models? Or have you done that before? Like with a steampunk idea, you could add stuff on top to take the theme further if you don't have the actual steampunk clothes and accessories and stuff for the model to wear.
I'm not even that familiar with Naruto's story past a certain point but when I read the title of this, I immediately thought of this part that I'm only vaguely familiar with. Then I saw the tags/keywords and confirmed it was what I was thinking. A proper title can add so much meaning.
I don't think you should be so harsh on yourself. It's a simple picture but I like the kind of minimal look of it. I think what's there is done nicely and the white on black approach works really well with the scene.
