I downloaded these as I prepared to start RotRL midway through with my lvl 7 party. I was dreading having to use a hodgepodge of different plastic minis, but then I found these.
The artwork itself is a little bit cartoonish, but it's good enough for me. I printed these out on 110 lb. card stock, used a pair of scissors to score them, and clear Elmer's school glue to glue them. Since I first bought and DL in late April, a few changes were made. Some hags were med instead of large, and the black maga artwork was made MUCH larger.
Here's a picture of a few of the Grauls and some of their pets.
This is a great product for DMs who don't want to spend a ton of cash to get plastic minis, but like to have minis more specific than, "OK, guys, the troll is actually an ogre, and the chaos beast will be the tentamort. . ."
The art does have its own style, which may not be to everyone's liking. But my group finds these very enjoyable. They are not too difficult to assemble, and they are cheap enough that you can actually print out that army of ogres to attack the Party.
I particularly enjoyed the Huge minis in this set, the Tentamort and the Mother of Oblivion (aka Black Magga). The ogres are the other highlight of this set, and there is a good variety of them (although pages 8 and 10 seem to have the exact same spread of ogres. I'm not sure why they are duplicated). I was a little disappointed with the Black Arrows; I would have preferred them to look a bit more haggard, based on how they were described in the module. But I suppose this way they can be used longer, if your PCs end up convincing them to stick around.
All in all, this is a well-produced product that will see a lot of use at my table. I can't wait for the next set!
