Thanks everyone. Your thoughts are appreciated. I'm not a fan of oversharpened images, Morkel. (Probably a personality quirk or lack of good taste on my part). No additional sharpening was done after resizing for web use. I imagine that an additional dose would bring it right up to what you're looking for. Maybe I can get myself to start running a sharpening after resizing for web use.
Sorry about the mane, Jamie. I forgot to bring a hair brush with me.

Another mare tried to climb in my kayak for a ride so this one might have let me close enough to brush it... but I'm too big a chicken to really try it! The more time I spend with these animals the closer they seem to allow me to be. Mind you I don't move in closer to them, they wander in closer to me.
Again, thanks all.
