I really have my scene nailed down pretty tightly in terms of design. I made a character sheet for my ghost girl and will begin modeling her soon.
I also look up techniques on creating convincing yet low poly flora. I have not decided on my ultimate tri-count, but I would like to keep it fairly low so I can really test out some techniques on high-poly to low-poly modeling and show that I have the chops to make beautiful game assets that aren't poly heavy.
(By the way, the title comes from the Yu-Gi-Oh abridged series. I highly recommend it).
