Personal bias is here to say a few words, the legs on your little bunny are a bit long, it's cartoony, right? but you have a defined knee joint on the leg, so it creates a disparate uncanny feeling. You seem very much to be going for that loose squishy rubber hose type of stuff, so I'd do what they did, ditch the joints, that's why it's called rubber hose because the limbs are hoses, that or contain the proportions and movements to get out of that uncanny territory. Music choice was cool though. I think you've got the technical skill, but are missing out on the tactful side of things, yah gotta make choices in the style that gell with your other aspects to create harmony in the whole product.
