Butterfly art

These works are unreal, there done by L Fillpe Dos Santos’s (another artist from http://www.behance.net/Gallery/See-_-Saw/56191) What artist does is do a ink butterfly picture in a book then go over it with line work. Creating some awesome designs. I really respect the drawing skill this artist has. Its something that would take me many goes to perfect an image, and they have done its first go, he has to as you only get one go at each butterfly print. Again ink and water color look is something I really like the look and texture of.
