Hello, you might want to work on the Call to Action button/link. For me there was no clear indication where I should click to try it out.

Also, the text and logo at the left don't seem to be centered in the left "region". It seems too close to the screenshot to me.

In the program itself, this http://i.imgur.com/I6oHv7c.png seems really confusing. The pointer makes it look like I can actually drag it, but that's not possible.
