Love those last minute entries, if you don't submit the wrong photo you spell the title wrong. Oh well.
Some folks saw the vague blurs as smudges or reflections off a window; Ugly as they are, I disavow most of the blame as they are the vertical elements of the rails, blured into vagueness, I tried to pan even further to lessen them, but couldn't hold the pan that long.
A GREAT motion stop picture. I love the blurred background (I'm assuming you panned with the horses), as it really makes you FEEL the motion.
However, the misspelled title suggests that you didn't put much thought into it... which I know isn't true. Even if English isn't your native language, it's important that the title be correct. Check out dictionary.com if you're ever in doubt. :)
6 - Wow. Pretty amazing shot. Criticism; seems you took this through a glass window(?) as I can see what look like reflections. Really like the effect in the movement in this shot, especially the 'smoothness' of it, coupled with the colors. As far as the Challenge and this being 'even', (even an 'even field' (no pun)), it is a bit of a stretch (again no pun), but there are other 'even' elements in this shot. Very good coloring. Title typo, which you likely know by now.
