Prints: Should I Do Them?

I have finally enabled prints of my DeviantArt works, after some complaints from my local friends convinced me to try it. I've never sold prints before, I don't think I have enough attention to sell any in the first place, and I'm not 100% sold on this DeviantArt print service, but then again, I've no experience with it at all, and as my friend said, what do I have to lose?

So this is a bit of an experiment for me.

Right now, I have prints available for "Link" www.deviantart.com/print/16651…? and "Snow Cranes" www.deviantart.com/print/16541…? .

I could enable prints for any of my other works, no problem. I have high-res versions of all of them. The question is: what other works should I enable prints for?

Or should I just not bother with the whole thing?
