If you don't mind me saying I think you need to get out of your comfort zone and talk with people about your product. It will make a massive difference and you will not be finding out 2nd or 3rd hand what people like and don't like. Thats what I did years ago with my first one and it made a massive difference. I was naturally shy when younger (as many people are) but conquering that made a huge difference. Good luck with it
