As the title says, I've now taken the concept sketch that I did and have now roughed out the model in 3DsMax for a day. I'm rather happy with the result.
Some more adjustments to the Timmy model due to some added critque. Got rid of some of the folds that didn't make sense and I've also added some buttons.
If the title didn't already give you a hint, Blizzard has just announced that they're doing a art contest for students. The winner gets a three month apprenticeship with a working Blizzard artist.
