Crochet Uni Hat

I made this crochet unicorn hat.....and to me it's one of those FAIL projects that you see the jokes about.  I'm not happy with it at all.

Here is the pattern I used to make it.  She is much more talented than I am.  I'm still trying to decide whether to try and sell it in my shop or toss it in a bag and forget I even made it.

Comments from friends mostly were that the horn needed to be longer.  I agree, but that was ALL the yellow yarn of that color I had.  The other comment I got was that the mane looked more like hair.  I agree with that too.  

Any suggestions?
