I love monochromatic! I did this in Photoshop by the way.
Here are some things I have been working on that I have yet to show.
Above is something I did over a year ago. There was a brochure that Heidi had retouched, and it had little pictures, maybe 10 or so. The assignment called for this particular thumbnail to be blown up to a printable size, but the original scan was so small that it looked horrible. I was given the task to paint over it to make it look good enough to print. It was quite the job, perhaps the most labor intensive project to date.
