On the MOC side:
Group B: Ultimate Kardas
Group C: Akuna Toa of Sonics
On the Art side:
Nyert, definitely. The others are fine, his is just much more clean and professional.
On a side note, that was a bit of a poor decision, putting MOCs into three different groups, and then only accepting two MOC votes. If anything, it should be the top two MOCs from each group going into the finals, allowing everyone to vote for one MOC in each group.
