Cute stuff! love the style and expression. if there's anything constructive I could say, it'd be that it lacks some contrast. The light lines soften the drawing too much, maybe have some darker linework at play with it. Or maybe have a contrasting background color to keep it from blending into the background. I definitely loved the yellow hair, it added a lot of flair to the drawing, It might be neat to experiment with more yellow flares in the drawing to bring the colors to life. Overall it's awesome work and I hope to see more from you.
