Bus Wrap

So for one of my last Illustration classes at SCAD, we are creating a design for a bus that would represent the Illustration department here. Other departments such as the sound,photography and animation ones already have buses , but at the moment there isn't one for Illustration.
So, the first sketch was what i initially started drawing as an idea of a face/skull/mask design that I thought would look cool with lots of bright colors on it..

it then developed into more of a 'wrap' with the left mask being placed on the left side of the bus, the center mask on the back of the bus, and then finally the right mask on the right side. The hair will connect all 3 faces.

the image above was roughly drawn with a ball pen, just to get my idea down..

& this is what i have thus far..composition wise. I'm stilll debating how im going to execute it and what colors I should use...though I have some ideas floating around in my head :)

this should be fun to finish ! :D
