Your transitions from between the different sections doesn't seem to flow very well. I would try and make the middle area flow a little better, it seems to be breaking things up quite a bit. Think about confining the top section, "Automate your practice" into some sort of box treatment. Good start here, just a few tweaks and you'll be there.
give two colors gradiwnt not blue-white and blue..
typo need to be improved
i spent most of my opening seconds trying to figure out what your they did. i think the message could be a bit clearer. i don't like the block formatting of the text. and the talk bubble could look a bit better.
also i think you might want to widen the site a bit and add a right navigation of some sort. right now as it stands it looks like a half way there - website.
