My first thought here would not be of temperature, withouth the title, at least. Seems more like an attempt at using humor to tie a nice photo to a challenge. Anyhow. Very cute foal. Pretty colors, love the swishing tail. Since there's a lot of sun and shade, there's a really good potential for dodging and burning after the challenge to even things out. Especially the foal's head is too dark at the moment.
Cute picture, and fairly well done. I am not one of those that penalizes outrageously for stretching the challenge, but this doesn't make me hot or cold. 5
The only thing that conveys temperature here is your title. Otherwise the focus is a little soft on the pony and/or it was shot handheld with a slower shutter. Tripod would be beneficial if you want to maintain the motion blur of the pony. Faster shutter could make the subject a little sharper. I like the DOF element but think your background is a little blown out. 5
