prints sell just fine however there is no one thing that sells more than the other. it all depends on the collector. it's best not to over think it or game the system by providing things you think people will buy. it's too frustrating to follow and it doesn't work. its better to upload what you have, things that are of high quality. things that sell will make you shake your head - anything from swamps, cacti, small dogs, clowns, toilets, etc. anything can sell to the right buyer. but there is no one single thing that sells best, and if it did, it would be a closely guarded secret.
be sure to add the right safe filters for the work you have.
