This is a great website! Mainly because the quality of the designs you picked are great. My only feedback is that it was hard for me to find the button that takes me to the website for each screenshot. It was very important for me to actually find the live site rather than a screenshot. Animation, loading, transitions are big part of the design that won't be shown through a screenshot.

I'm not sure if it helps but my team an I are working on a project that you might also like the design: servicebot.io (wait for the parachutes :)
