Kazuki Muto

This is a fanart i did yesterday in about an hour and a half - it is my third fanart ever (i am only 13 and been reading manga for about 8 months or so), it wasn''t too hard but the shading on his clothes didn''t work well. I don''t own a scanner so i had to photograph my work on my phone and upload it p[lease ignore the quality.
Kazuki is a cool, determined guy and i think this picture shows that well - What do you think?

I have only done four peices of art (been doing it for a week) and they are small but pretty good - Am i intermediate or beginner?
