Artist, Rafael Vallaperde has an incredible knack for creating human emotion in characters who aren't necessarily human. For CGSociety's CG Challenge-Ten, Rafael created this wonderful piece featuring three extremely drunk aliens enjoying a little bit of weekend partying. The detail put into the piece is mind-blowing, and I highly suggest you jump over to Rafael's website to get a full look at it.
On top of the incredible piece, Rafael has also released a 'Making of' video, showcasing his process. The video in itself is amazing on it's own and gives a detailed look at the process of creating a piece such as this.
