Speeder Bike Paintover

Today's first post isn't a sketch or doodle as such, it's a paint over I've been playing about with of a Speeder bike I made in 3d.
It was made for a 3d modelling competition which was held a while back through the website SimplyMaya.com.
I actually won the comp (most pleased!) so thought it would be a good model to try my hand at doing a paint over on.
All that has been added is the colour, and the dirt, mud and scratches.
Not too bad for a first attempt, maybe I'll look at doing more to this at some point, but for now I want to do some drawing!, so hopefully there'll be a second post later on today.
