I was taking pictures of my dog running the other day, and realize how hard it is to get sharp focus of a running animal, even with autofocus. Nice. I also like how you've managed to keep the detail in the white horse. Good job.
did you bump up the saturation, or are those bushes really blue? Very cool capture though with her in mid gallop.
Maybe convert to B+W with red filter and increase the shadows a bit.
6 - Nice capture. Perhaps cloning out the minor distractions, or even cropping (not sure), may have given this even more. Nice mix of colors in this image. Looks like good control of the whites in / on Redcloud.
A really cool catch of this. too bad challenge rules don't allow you to add some wings to him! The field above his head is a little distracting, but you could not exactly pose this shot!
Wow! This is just different! The colors and depth of field and the bizarre stopped action with the horse in the air but looking directly into the camera are just cool!
