The foal was a nice idea for a subject but several things take away from it. The lines of the fence, the dominance of the landscape in general, pull the eye away. It appears the focus is on the house rather than the foal and, in general, it could use some sharpening. Shooting from a different position to help isolate the subject, limiting depth of field to bring the attention back to the foreground, these among other things could help. Hope you have an opportunity to try this subject again, it's full of potential.
Your composition is very nicely done. Unfortunately the colors seem a bit bland, I wonder if tweeking levels and saturation would put more WOW into this shot.
Very nice compostion, however the focus is a little soft and the horizon needs to be straightened. With the challenge focusing on your subject being the strong point, the foal gets a little lost being in front of the house. Maybe a different angle, (i.e. without the house) or a little tigher cropping (for example have the foal framed in the upper right and straighten and crop the image to just above the fence) would have increased the focal point onto the foal. This along with a little crisper result would improved your result in this challenge IMO. Good Luck.
A somewhat pretty picture, but it has too many potential focal points. Animal? House? Barn? Field? Minimalism should be very simple, with the focal point very obvious. Also, the animal is sufficiently indistinct that I'm not sure what it is. Young horse?
