Lansdcape and Non-Sports Photography?

My sister is the CEO of two small art galleries, one in Hagerstown, MD and the other just recently opened in Gettysburg, PA and she has a proposal for me. They have space available for "rent" at Benjamin Art Gallery and they would like to try selling framed photography in the gallery. Basically I think they are looking for landscapes, abstracts, travel and other non sports art. I threw together a quick gallery for them to review, nothing fancy, and they are interested in more. I am not sure I want to spend the full rent but maybe worth a try. Here is the gallery I put together. Let me know what you think of them and this idea.
