* You're using what I would assume to be your hilight colors a bit too strongly. It is great to use the orange for your CTA, but the orange and the green in the table are a bit overbearing.
* Your table columns do not align, making it potentially confusing to others that view your page. They might not understand you're making a comparison, which can be ploblematic.
* Your subheading font is too heavy, making the text less readable.
* The copy at the bottom could use some work. The messages are too wordy. Ideal copy in those areas should be simple, not too wordy, and really push your product. Potential users read this to judge your product if they haven't already been snagged by your CTA at the top of the page.
* Testimonials always look better with a picture. Even if you have to use a stock photo, it adds credibility.
* I just noticed, your page doesn't have much of a headline. Compare to http://artistsnclients.com, a project of mine. At the top of the page, there is a very obvious CTA, along with some persuasive headlining text. This should, ideally, explain your product in one sentence, and then make the potential customer feel as if they owe it to themselves to sign up for your product.
There's probably a lot moreto be said, but I can't be getting too nitpicky here. Good luck!
