Here are some really quick Matte Paintings I've done in the last days on my classes at the Metropolitan Institute of Art & Design.
My students rocks. Most of them have an awesome creative power, although there are always the ones that doesn't have a clue about design, and they pretty much just rock using Word or Excel. lol
Lack of some detail on these, for sure, but each one of these was made in less than 20 minutes, to explain the class and then watch them slowly doing it.
