That's pretty sad that you can't finish this competition, but...
Considering that the competition has a duration of 2 (two) month, I believe that you will manage to make something in this time.
Let say that you are busy one month; in second month you can make the project.
Be aware that texturing is not mandatory.
It’s up to you what you decide.
Cheers
