Quite a set you've got here. Too many to critique so I'll simply say that you've got some shots with promise. I really like the ducks. Pay attention to your composition, and I'd recommend bracketing the exposure...snow can be very tricky and often you'll end up with a dark, low contrast picture. Also...the snow tends to fool the camera and you end up with blue snow, not white...so you may need to adjust that a bit, too.
