Design Change Feedback

I've been thinking a lot about the main page of our various sites.

I identified a few problems:

(1) Doesn't change frequently enough since the most active thumbnails get "locked in"
(2) Doesn't have anything beyond the 16 most popular
(3) Makes it hard for newer members to get anywhere near the front page of the site

After a lot of thought, I came up with the following proposal:

(1) Feature a mix of both most active AND most recent works
(2) Emphasize both expiring challenges (so people can quickly submit for them) and most active challenges
(3) Emphasize the days top members, first-time members, and top categories

Once I had the elements in mind, I took a first-crack at a design:

Please take a look and tell me what you think here!
