HI, I took a look at your shop, although your views and sales are about par with mine :-) I like your things, they're pretty cool!! I do think that perhaps showing them in frames and or a mat might be a nice way to show the print for the main picture and then have the closer ones as the rest. Have you taken a look at other print shops to see how they showcase theirs? Sometimes that helps too...
