I think you need to make better use of the screen real estate. Having the feature examples below the break (Chrome, Mac) is not very effective. This app is in a crowded space (market) and I would move what you think is the distinctive features to the top and make them eye catching. Maybe thinking in vertical stripes with product, validation and features each having a column would be more impactful.

My eye goes to the gmail logo which I do not think is the message you want to communicate first.
