Sorrow certainly does become joy when you find an artist with a few skulls in his closet. In this case the skulls belong to Ekundayo, a Honolulu-born multi media artist. This fella has some wicked drawing and painting skills and he has been able to successfully translate these images from canvas and paper to large scale murals, using a mixture of painting techniques and spray paint.
The last image is a print (on German Hahnemuhle no less!) available to buy from his online store for $60. Be sure to check out his Tumblr account, Sorrow Becomes Joy, as he has loads of process shots, if you are into that sorta thing.
