This is a scanned and inverted sketch page of Cobalt as part of a trade some time ago. I kept the category as "Traditional" since it was originally pencil sketches that were done.
I took a scan of each corner of the paper then pieced them together. The full image is much larger than regular paper. You can see areas where the images overlapped.
I decided to invert the image. I think it looks neat like this and is less of a strain on the eyes.
The image has been reduced in size a fair bit for web posting purposes =)
