Great design! And I love the idea even if I'm not a big photo guy myself.

11$ seems a fair price if I'm hooked to your product but I need to try it before. Maybe you can offer a free plan, or give a trial period (10days for example).

Also I think that you should put your "View a sample collection" way higher in your homepage.

Good luck! I really love what you did, your design and your logo are awesome :)
