Dryland Sled Dog Race

[Beckerbulldog]

I shot a dryland sled dog race this weekend and I think this is one of my better shots.
What I need critique on is this;
1. crop to tight on the sides? - should I leave room on the right for the dogs to "run into"?
2. Should I crop out the dark area at the bottom?
3. Is the white dog blown out a little or is he ok?
Any other advice welcome.
Thanks in Advance.

Nice shot. I like the cropping as it is, it gives it that feel of them moving closer towards you. I don't think you need space on the right as the dogs appear to be coming straight towards you so they have space in front. I would've like to have seen the driver in focus as well but those two leads dogs are nice and sharp and they both appear to be looking at you which is great. Still undecided about the darkness at the bottom, I think it is the space you need but not sure about the shadow.
My 2 cents anyway, thanks for sharing.

I think the picture is very good, but as you suggest... crop more in the bottom...
