Sorry, that is exactly what I was looking for. Any help to improve is good.
Hey again, 63square. People become easily hurt when others offer opinions and advice that they did not ask for, so it is always best to err on the side of caution.
The first shot is way overexposed. It is always a problem when shooting dark objects against bright backgrounds, and it will take time to learn how to get a good exposure in that situation. Somethings you can do are, moving around to get a different angle where there is not so much sun reflected off of the snow, or if you see clouds moving toward the sun, wait.
When you do your post processing, try playing around with shadows and highlights to reduce some of the hot spots in your photos (or use the burn tool if you know how, I'm not any good at it myself). For posting on the web, don't be afraid to crop your pictures until you get some more experience. And, if you have a nice image that you do not want anyone stealing, post it with a resolution no higher than 72 (there is not need to post a pic on the net with a resolution over 300).
This is the edit that I came up with, with the first image, there are still some hot spots in it, but not so many,..
The second image, just has too much in it. You can compose your picture by cropping it after it has been taken, and soon it will start coming to you when you are taking the pictures (composing them, that is). I played around with the shadows and highlights in this image also, and tried to crop out as much of the "man made" objects in the picture as I could.
The mallard is the best of your shots in this thread, if the duck was a little closer to the bottom right corner, it would look even better. The pictures with the golden-eyes in them have snow that is over exposed and could be cropped out. When taking pictures of animals, try to take them with the animal looking in your direction, getting a good clear shot of an animals eyes makes a HUGE difference in how good the photo is.
I hope some of that helped.
