This is good... but not really a sprite sheet for a game. Why? Well there is no flow/sequence between frames is lacking. The first row on the last image with the bunny and the moon, you can see how the stone is missing on half the images (that is just one error). The design of the character is not bad, and I would rip it into my own animation flow. However, I would not use it as an animation tool, maybe using it more like a sketch board.
