WPMUDEV Themes for Photo contest blog

Dear great community,

I have planned to create a photo contest site in my sub-site network.
I have created the post structure as backbone of my site so the user that have registered can submit their photo post to the contest. Me as an admin will approve their photo post submission, and its worked.

But now I need your advice regarding themes. Actually I need grid type of themes to fulfill my expectation. Homepage grid that display featured photo posting with excerpt or little description and wmpudev post voting plugin (thumb up or down).

With my above description, please advice which WPMUDEV themes that can fulfill my expectation.
Your support is highly appreciated.
Cheers ...
