Hey it looks nice! I like the hands, looks soft and plushy.
Composition-wise, my curiosity is really drawn to that ball of lightning on the right. Probably because both arms are pointed towards it, drawing my attention there. So it saddens me a little to have it cut off. If you cropped this picture, may I suggest that you 'slide' the frame more to the right? (I should also mention that Iku's head sits square in the middle of the frame, which happens to be the least interesting place to put important things a la rule of thirds.) If not, I hope you can take something out of this to plant in your head for future things.
You should continue to do things that feel good, keep picking up that pencil, keep drawing!
