Here are my initial ideas after just glancing over the webpage...
First... The header image is not very attractive. I would personally get rid of the header image all together.
Second... Put the headline in red so that it stands out. Red headlines have been proven to pull the best. And move the ecover graphic down on the page so that it doesn't distract from the headline.
Scrolling through the page, I don't really see a good list of true benefits for the product. I would write at least 10-15 really good benefits of what the buyer will actually get from the product and use POWER words to really get them excited.
It doesn't look like you have anywhere on your page where you're attempting to build a list either. Most people aren't going to purchase from you the first time they visit the page and if you're paying for adwords, you're basically throwing money away by not building a list. Try a popup offering a free mini-course.
There are also some spelling errors on the page... Make sure you go through it with a spell checker.
If this is a product that you created yourself, you should tell some sort of story about why they should listen to you and why you know what you're talking about. Let them know who you are and give your readers a reason to trust you.
