Really very good, nice work! ;-)

 Much much nicer. Good job.

 gah! I didn't even think of putting shadows under the trees! still time to edit before the challenge is over, thanks.

If im not mistaken, it looks like this man dropped trou. :p

Loving the sand dunes, very well done on the shape. Would be cool if you used the same shadow technique under the trees. You've got good perspective going on in the background, I think shadows under the trees will really tie this one together.

Good job, I like it.
