Wow! very nice photos. I love the style of the first and third--their simplicity with the contrast of the dark, dry plants against the snow. In the first photo the leaf that curves back into the snow provides a nice visual line in contrast with the straight stalk. The middle photo has a much different character to it that distinguishes it from the other two. It is not so simple as they are. The shapes of the snow give it a very sensual quality, and the small hole invites wondering, What little creature might go in or out of that hole. It is perfectly composed with the visual lines flowing at a diagonal across the picture frame rather than horizontally. All are really nicely done. Now, if only we'd get some snow here in Indiana so I could get out and take photos.
I like them. The last one is the trickiest since there is almost no detail (at least in the jpg) visible in the snow. I might prefer the snow a bit whiter, but that is easier to work to with a bit of detail to suggest the texture/form of the snow... detail that you do have in the other two.
