Starting with the most recent, here is the 77170 Clay Golem:
I went for a somewhat "red clay" look, but ultimately I didn't make it red enough. The biggest challenge was getting a "clay" effect that didn't just look like a fleshtone. When I get time, I may go back and try to add a little more red to further distinguish it as clay.
Next is the 77136 Well of Chaos:
The carvings and relief on the well reminded me of the Cthulhu Mythos (the recent Cthulhu Wars Kickstarter campaign probably helped with that, too). As such, I was aiming for something a little alien in appearance, and I'm pretty happy with the odd blue-green color I wound up with. This is an excellent miniature, and can be painted up in a multitude of ways and still look great.
Finally, my first entry to Monday Miniatures, the 77146 Mummy Warrior:
