Can someone tell me if there is a simple thing I can do to improve my landing page's loading times?

I understand, just making sure that they were indeed a proper size, which seems to be the case.
I suspect you could also improve loading time by cutting back on some of your animations like on the star ratings, but honestly I loaded the page just now much faster than before on a different browser without the cache and it loaded much more quickly than before which leads me to believe it’s something to do with server loads.
