I like the layout.. there are two things I noticed that might make it look a bit more professional and a bit less like a huge advertisement.
First: Your sub header with the picture and the free video text is way too big. It completely takes over your blog and people will click away immediately. It is too in your face and that turns people off. Reduce the size of the sub header a bit.. You want people to click on that, but they won’t if they don’t read the content of your site… they won’t read the content of your site if they think your only goal is to sell them something.
Second: At the end of the page it has a section that is named “About the Author”. It is currently blank. If people see that they will immediately believe this is just shell website with no internal meaning to it. They will navigate away from it once they feel that the author doesn’t want anyone to know who they are.
