1. Not too sure about the title "Kiss Your Complicated Help Desk Software Goodbye!" as well as the statement below it. Big words, which can easily be replaced by smaller words and more images of the product.
2. Not a fan of Serif and fantasy fonts either. Try some Sans-Serif fonts instead. Will make the copy more legible.
3. The boxes which show product features look like blobs of text. Use images with text. Keep the feature boxes less and instead give a link to a separate "Features" page.
4. The "play" button image on the video looks odd. Doesn't gel with anything else on the page.
5. Put more testimonials and put shorter ones on homepage. Shorter ones tend to have more punch. Make a separate page for testimonials where you can allocate the bigger ones.
Really dig your product by the way. All the best.
