The groupon starburst is trite (as are groupon clones but that is another matter). You obviously stole this artwork which strikes me as sleazy. That said, you are selling knockoffs so maybe it helps you.
I would kill the fixed green div in the corner. It distracts from your main content and it is redundant.
The shift from starburst background to #fff is a visual shock. I would soften the light bulb and add some borders.
When I opened the site in Firefox I got prompted to install missing plugins. Drop whatever is causing that. And whatever c.mouseflow.com is it's killing your load time.
The headline is worded well but the big serif font on that stark background is a bit painful. Go smaller and softer if you can.
Try moving the video player and the text around until you can fit everything into the center space. Right now the player is shifted off that canvas and that looks weird.
I would showcase the example website. Right now it's in an iframe, and the resultant UX is confusing.
