Static - Nicely focused Meerkat, you've got the eye in focus too. Perhaps a little central?
Game - Great bit of action there, but ouch, how is it so noisy at iso 100? Is that some kind of grain effect, or a result of cropping? Sorry, I don't like the muted tones either (I initially thought it was an artifact of high iso until I checked).
Serene - And then suddenly boom! Same camera and lens. Higher iso (500) and yet a much much cleaner shot.
Spot on theme, good use of the trees to frame the shot and a diagonal leading line which draws the eye across the image. Winner!
