With regards to the 60-80 images. Analyzing my Google analytics it would appear that the average time spent browsing my site (which contains over 150 images) the user is spending anywhere from 6 to 15+ minutes browsing. These hits are turning over into contacts and sales. Although some are anywhere between 1 and 3 minutes. I simply put this down to a lack of interest in my style of work. Which is inevitably going to happen. I wouldn't put it down to a lack of interest in the site itself and the amount of images it presents.
If you are going to show from 10-15 images to try and sell yourself as a photographer the work needs to be on par with the top professional photographers of the world. This in turn sets the standard of the webpage requirements so high it is barely obtainable by the working / semi working and or aspiring amateur photographer.
I am fortunate to have a brother who works in internet marketing. His portfolio is vast and ranges from Expedia to Tesco. He ranks my site very well (and that's not because we are brothers, my previous designs were shot down like sitting ducks with many swear words). Yes my advice is
second hand but it comes from an insiders / knowledgeable source.
I personally think your re-design needs a lot of work. It doesn't show creativity, professionalism or more importantly individuality. There are a billion and one sites that look the same be them blogs, basic layouts or how they are presented. Break the mold and it will pay off in the long run.
