As far as D&D fan creations go, this one is right top there among the best. Some of the folks over at Reddit have combined efforts to create a collection of new monsters, with full colour artwork and stat blocks. Currently 91 monsters strong, you can download the PDF completely free. Monsters range from the
Clockwork Pest at CR 1/4 up to the
Umalog, The Ceaseless Hunger at CR 30. Others include the Fusion Elemental, Gnoll Deathknight, Ice Golem, Magma Bear, and many more. The stats were done by StoneStrix; the art by a wide range of folks.

I don't often go to Reddit, but there is one exceptionally good section for 5e that I like. That's the Monster A Day section. They now have a PDF of their work, complete with a cover. It's basically like a Monster Manual 2, with all unique monsters. They're at 91 entries now. All are like a page out of a monster manual, complete with formatting and artwork and full stats, and many have strategy/tactics/background sections as well.
It's free. I think some people might like it. Check it out (accessible in two locations):

or

Both continually are updated (though tend to be a couple days behind the newest monsters.
There is also an image icons list for the PDF.
And a
Fantasy Grounds module for the PDF.
