anything has a chance at selling as long as you market them. looking at the images - they seem all over the place. not enough of any one theme to let my eyes settle. the colors are everywhere as well, and nothing is all that straight. while a major tilt is ok, a tiny tilt will drive people nuts when they try to hang it. you have no locations, and the titles are a bit bland, and you have no descriptions. people are interested in towns and such and not telling us where it is, will hurt sales. calling something blue day and only having 5 keywords, won't help you in the slightest at being found.
be sure to add a bio and advertise the work though - no one will find it otherwise.
