Personally, I liked my symmetry entry way better. I guess it's hard to really gauge "progress" yet, cuz I've only entered in 2 challenges now, but it stinks to go down. Oh well!
Keep your chin up. You'll figure out this DPChallenge thing if you keep with it. You'll probably look back at your pics in two months and see why your score didn't meet your expectations. This is a great place to learn. Hopefully you're receiving good constructive criticism.
I'm in the same boat. In just the first two days of voting I had more than double the comments from my "Symmetry" challenge than I did for the entire "Time" challenge. At the moment I have 3 times the amount of comments (all positive), yet, it is scoring lower than the "Time " challenge. What's up with that???
