I would invest in a cheap printer with a scanner built in from like OfficeMax or Staples.
Getting a printer with a scanner is a really good thing to have, especially since something like a Canon MX490 can do scans at 300PPI and higher.
Anyways, I really think you got down the form really nice in this illustration.
And the shading is lighter but still gives a nice feeling of 3D.
I think you could make it more impactful by making the clothes more aggressively shaded.
People are drawn to art that has some nice lighting + shading.
Anyways, hope you find a solution to the photo issue!
