Phobia

I am currently taking a creative writing class and am really not use to writing at all. I would really like some feedback :) This is a short poem called "Phobia", as you can guess, it's about spiders.

Twinkle Twinkle little star

Icky hair and skin like tar

Up above my bed so high

How I wish you’d all just die

Twinkle Twinkle little star

I’ll just put you in a jar.
