1. No Textures,
2. Lighting allowed,
3. Wireshots from various camera angles,
4. Progress shots of the model from the beggining,
5. Present concept drawing/ picture if one is used,
6. Finish in one month :p ,
7. The *.mb file is really not needed, unless you want to show it off..

p.s. If somebody wants to texture his model, he is more than welcome but it WON'T count, the final render must be WITHOUT textures.
