Don't it will happen (sale) when you least expect it! I do agree that you have to have min of 1,000 pics in your portfolio before you and really compare stats. I have only 190 thus a lot more pics to get into my portfolio. I am finding out as time goes on I laugh at my early pics - poor comp, lighting and concept. Thus with each month I am gaining leaps and bounds on this stock world. I have a lot to learn about lighting and composition thus open minded to all comments, articles, books and videos...
