Hi Mikwd. The silhouettes look extremely effective against the white backdrop, which gives them an almost 3D effect.
I know that the site is under development, but the one thing that is missing is the item description. Potential purchasers currently have no way of knowing what material they are made of, whether they are rigid or flexible in their construction and whether they can safely be used outside without UV degradation, or what the estimated lifespan is if used outside, I also have no idea to their use, or where I would situate them. The more information you put on there, the higher your sales conversion rate.
You also need some basic information on your cart page or elsewhere about your shipping methods. That is especially so for international orders. You should put information on other pages of your site about your trading terms and conditions, anticipated despatch times and your returns policies. Most countries have online commerce directives, which is a basic legal requirement for mandatory information on a web site.
Despite the above comments, the products themselves look very good though.
