A bit surprised that this scored under five! I think that your idea is good and "Waldo" is well hidden. Is your friend moving, or is the snow which makes her kind of out of focus? Either way, it is effective. Composition is good, there is a good balance.
Technique
The colours seem a little washed out, was it actually snowing at the time? If so, I can understand the overall fuzziness. Perhaps a little more contrast would have added a bit more imapct and I wonder if a bit more sharpening would help the individual trees stand out.
My opinion
I think that this is a lovely snowy scene, perhaps a bit more detail would be good. You have met the challenge well and taken a lovely picture. Good Luck in the next challenge.
Hrm...well, not sure if there is a Waldo in this photo. There is an area with some different coloring...but it isn't obviously a person. Otherwise, I think the photo could have used more contrast.
Best place to hide Waldo. Right out in the open - in a snow storm. Great job and a beautiful photo. Is this full color? There appears to be a little red at Waldo. Nice job.
Lovely snow scene. I almost called this a Black and White until I looked closer and saw the color in it, especially in your coat. You've done an excellent job. Just out of curiousity, what is that to the right of you, in the snow, the dark object? Looked like it may have been a dog laying in the snow.
Nearly a snowman in a snowstorm! I see your waldo, on the horizon, 1/3 on the right. Is that a sled with waldo? The snow seems to have "fooled" the camera into thinking there is color (my guess). 7 Swash
I see Waldo standing there nearly blending in to the trees. Good job. What is that black object there next to Waldo. It would have made spotting Waldo more difficult had that object not been there. Good idea.
