Good image, but either she's too big or the horse is too small.

I think the ponney is too little. Good use of the source image.

thank u for ur comments,but i did it in a hurry..lol,was scared i wudnt finish on time. I dont think i'll have time to correct the errors now

Ok, let's make believe it's a mini ponney (smaller than a ponney).
Nice image (a bit cruel, but nice)

Author, you have until the contest ends tomorrow to post a revision.

The idea is kind of funny (woman's reaction), but the horse makes the scene too serious. Now I think, poor horsey, he's killed .... If it was something like a unicorn it was still kind of cruel but more in a fantasy way/surrealistic, I think it would have looked more like black humor. Just my opinion though. Good luck!
