Cute...

i like this, maybe make the cat's head coming out of the bulb and increase its size just a little

This is really cute

this would look better if you cropped around the kitten to draw more attention to it

Why the zipper? The cat's head could be coming out of the bottom opening.

Thanks for the comments and votes, I considered having the kitten coming from the bottom of the bulb as CMYK mentioned but i just wanted to add something more so i went with the zipper.

add some concrete shadow on the mouth and nose of the cat, make it gradient from bottom to head and fading in it's way upward, cat can not be so lightened in it's current case, good luck
