A bit small of a view (please use a larger frame). Contrast between the forest and the bone skull isn't very strong. Focus - hard to say, I can't see that much.

If you have to crop really small, you might try resampling up to a larger display size. If you're not familiar with this, check out the DPC Tutorial at

you should use more of your allowed pixels to display your shots. :) Would make it easier for us to see what amazing thing you've captured on digital film!
Way too small - you're allowed a dimension of 640 pixels on the longest side. If your file was too big, increase the amount of JPEG compression (i.e. reduce the quality) when you save your file with your editing software.
This shot needs fattening up - at this size it's really too small to make out even what it's of! Could have done with being at least twice as large as this.
Interesting approach to the challenge; I would recommend submitting a larger shot, though, both in file size (better resolution) and overall image size. Unfortunately, it's tough to get much of a look at what you're trying to convey.
I don't know what it use to be, i don't even know what it is now...
It is too small and dark. why did you make this so small?
next time make sure that the audience is able to understand/see the picture.
