An interesting approach to this week's theme. This is a good idea. Some people may be a wee picky about those jaggy artifacts, snow not being white enough and no technical actua; presence of a person. Bah humbug. This is good creative effort in the right direction. Extra points from this corner for not stating the obvious.
Photo appears to e over sharpened. I don't understand the dirty grey color to the snow, if it is for a reason. Right now can not spot Waldo and will have to come back to see if I can. For the photo in itself, it is not well done, very crowded with footprints, etc. As I said, over sharpened, out of focus, grainy and overall not real clear.
I think this is perhaps a little too abstract for the challenge. Is there a person actually in this shot? Also, why such a small grainy image with artifacts (especially on the right edge).
Footsteps.....it's beyond hiding (IMHO), this is more of a suggestion that a Waldo may exist (sort of missed the concept of the challenge IMO) Very small image with lots of JPEG artifacts (jiggly lines). 4 Swash
The original might be a nice shot, but I can't see this in your submision. IMHO this photo is much too small and unfortunately the JPEG compression artefacts are completely destroying the impression. You can submit a file size up to 150KB (your shot has only 15KB)! Doing so will eliminate or decrease the compression artefacts...
