I created this drawing using only my Intuos Tablet and Photoshop.
I tried out a new illustration technique today. I used a brush pen that I got for Christmas to create the original black line layer. I then placed the black layer on a light table and painted the other color layers each on a different sheet of paper using the black layer as reference. After all the layers were painted, I scanned them in photoshop into a layered PSD and lined them up, did some tweaking with masks and adjusted the color of the background and this is what I ended up with.
