What should I do with this drawing?

A few months ago the Society of Contemporary Craft in Pittsburgh commissioned a Sweet Meats installation for their EAT Space gallery.  One of the things they wanted was a life-size drawing of the inside of a meat locker.  The wonderful women of Avedano’s butcher shop let me take some photos inside their meat locker, and I drafted up this 18” x 24” image.

I had to make this image 16 times larger to be life sized, so I placed a roll of paper on the wall, and set up a 4” x 4” grid (I could only fit one half of the drawing on the wall at a time).  The last time I made a big grid to enlarge something I did it the stupid way, and drew the grid lines directly on the paper with a pencil and a ruler.  This time I was smarter and used thread and drafting tape (like masking tape, put peels off paper easier).  It went much faster and I didn’t have to erase anything later.

The big drawing (8’ x 6’, oy) is in Pittsburgh through March, but I inked, scanned, and vectorized the little drawing for printing.  I thought I might turn it into a paint-by-numbers kit, but there aren’t enough color blocked areas and too many lines.  So now I’d like to ask you folks: is this image interesting enough to print as just a line drawing, or does it need some color (or something else) done to it?  I was hoping to have some available at my holiday fairs this year, but I can’t tell if they’re compelling.  Would you want one hanging in your space?  Please be honest, not kind.  Thanks in advance!
