Thank you for the clarifications. I believe your structure might be the issue.
From a pure UX point of view, I think you might want to rethink the way you wish to showcase the review specific to each of your highlights. As a UI/UX designer, or simply a user interested in your services, it would be way more convenient to quickly be able to read your highlights within three or four lines - no need to hide what is important.
Also, your actual review seems a litttle bit long to read for something that pops up on hover. Why not try be as concise as possible, focus on what matters most?
If you still wish to showcase more info on hover, you might want to do it differently as for now, the entire layout gets pushed down rather quickly. Then comes the mobile design, how is you animation going to look like / trigger on smartphones ? At the moment none of the blocks are responsive. Of course I understand the screendesign is still in developement but this is something you might want to consider I’ve been there before.
