Zam,
Hi, I am new to A:M and the forums as well.
My first impression is that your request is a bit presumptuous.
Is this for college, high school, elementary school?
What exactly will you be doing for the school project?
When is this project due?
You already have the complete character model sheet.
There are plenty of tutorials that will walk you right through modeling Sonic. Specifically William Sutton's Zandoria Studios Youtube page.
Perhaps since you have A:M you can have one of your classmates model it for you.
I am actually going to attempt to model this character myself just to see how long it takes me as a complete novice.
All the best to you in your class.
