The theme (needless to say) is Christmas! For your scene you will have 5 models available from cgaxis for the occasion.
In order to participate you must be registered on facebook and join the group of CGRecord, and create your own album to post the wip and final images (maximum 2 per participant).
For all the details and the complete rules, we refer to the official page of the contest.
The contest closes on December 20. Best of luck!
