It looked fine to me. Simple colours and clear display. It will likely depend if you plan on adding much other stuff to the page whether it will stay simple or become cluttered looking.
I like this page. Very clean and good colors. My advices: ~ Do biger bottom margin. ~ U can add some small graphic in the text. ~ Maybe add colors from the logo to all expression "File Destroyer" at the text. It will look interesting.
I'd avoid using text highlighting. Maybe it's just me, but it makes me think of cheesey adverts and crappy affiliate sites - not a good look.
Another link to Paypal at the bottom of the page as well. Also would be nice to have some screenshots.
