I like the clean look and feel and the main colors - green and blue are working pretty well together. Also I think that the site is well structured, the spacing around the content is breathable and complemented with nice scroll animations. I can sense an animate.css fan, combined with wow :)

Also some of the parts of the sites are cleverly connected with the branding part - cloud animations and the cloud cta :)

My suggestion is about the UI consistency of the cta elements. I would suggest keeping one hover effect and keep it consistent across the site.

Great clean cloudy site/product overall :)

Overall the site is cute. The font choice, the colour palette, the illustrations are well blended. The tiny animations keep the site exciting and welcoming too. Maybe you can add hover effect on the Try It now button?

Keep it up!
