The colors picked are nice and pleasing to the eye. The shading is coming along well and the style is quite cute, but i must point out that the back ground is a bit distracting and going with a much lighter shade than the palette chosen is a wise choice most of the time. Having both stripes on the character and background with similar shades is also confusing and having them be different shades of would help with that. Over all the work is good for a growing artist and i'm sure over time it will get better.
Keep practicing on the anatomy and palette of your work to better your work and it will help on the long run.
