Here's an interesting piece I never thought about submitting here before.
This is a commission I got a few months back from a guy who doesn't have an account here on DeviantART. It was intended to be printed and shown at his friend's wedding (the newlyweds are, of course, at the centre of this picture). The sides characters are the commissioner (the groomsman) and his girlfriend (the bridesmaid). The four of them like to play Mario Kart together, so you can pretty much make the connection here.
I didn't hear from the commissioner since the wedding's day passed, I hope everything went as planned for them!
Paint Tool SAI + Adobe Photoshop CS4. Can't remember how much time it took to make, but by looking at the karts I'd say I spent A LOOOOT of time on this.
