Cute style, but the colors are quite similar so it blends together too much.
Try making some parts much brighter and use more contrasting colors.
Also the character is shown from a front-facing perspective, you need to show more of the top of the head and less of the body.
You might also want to tone down the outlines a bit, every single thing seem to have outlines.
Removing the outlines in certain places and using shading to convey the shapes would make it look at lot cleaner.
