The problem is, you are talking about art. And art is in the eye of the beholder. There are plenty of people who will disagree with your opinion and chosen fonts. I like all the fonts you used but don't like how they're used in your example.

So this becomes similar to a color palette site where someone shows a bunch of colors that you purportedly are able to use and are told they work well together. Until you use them together on your site and find them to be garish/boring/loud/goofy/amateurish/etc.

Of course, this is why we have typographers and graphic artists.

btw, if you go to real typographer web sites, you'll often read some groaning about Google fonts and you'll see that few, if any, use them for all the reasons they groan about them.
