Goose I agree with Rem on the high ISO -- when I looked at the pic data histogram they were on the high side for over exposure and on the soft side for detailed image (sharpness)
Here is what I was able to do and how using Microsoft Digital Image
Lightened the dark pixels, increased the color saturation to make the colors more vivid (same tint's just deeper), sharpened the image and adjusted the horizontal (straighten) just slightly for the far water shore line.
Results are similiar to Rem's -- increased saturation (more color), sharpened the picture, I could not reduce the snow glare without washing out the birds, removed some black spots that were in the upper right corner (birds maybe?), straightened the picture slightly based on the field horizon.
For this one distance and motion were the problems and I sharpened the impage.
These are a couple of pic's I took with my old Fuji FinePix --- (great little camera until I froze it
I will try to explain what I did with this camera as it was really limited in its capabilities.
Best pictures were at distances of about 8 feet with the sun on the object. I would have used the software to increase the saturation on this shot and sharpened the image.
This shot was an early overcast morning -- no flash. Again software for saturation. I did have to use smart erase to remove my feet from the frame as I was that close to the dogs. Lower left grass is cloned into the frame.
Hope some of this helps and if you get a good shot you want a touch up on send it through and we can PM back and forth on adjustments you want.
Keep at it as this digital work is addictive ---- oh and lots of pricey toys
