Just a suggestion here but... you might try adding a larger/brighter image of the chair as image 2 or 3, showing the detail of the chair, and allowing them to see how well it will work with close up/day scenes. Another thing you might try doing is posting in the product showcase forum/gallery, with your chair in a scene ;) helps get people intrested in it. It looks like a nice chair but I can't see the detail very well myself in your image. Just some suggestions ;)
