Here is a new illustration using a scanned texture to enhance a typically flat illustration completed in Adobe Illustrator.
The black line drawing was taken from one of my sketch books. I scanned it then brought it into Illustrator where I traced it using the fabulous live trace feature. Still in Illustrator, I added various blocks of color, playing with different levels of opacity for each one. Finally, I added the texture, a tif image from Photoshop.
The original texture file is a digital photograph of my sidewalk in front of my house.
