Thanks, all!
Yes, I was surprised by the size of the Wizkids gnolls. I've heard people complain that the Frostgrave gnolls are too small. But they seem about right to me; they'd be about 7' tall if straightened out, which matches the original Monster Manual. But the Wizkids gnolls would be about 50mm if they straightened up even slightly - so 10' tall or so.
Here are three quick adventurers: painted start to finish yesterday and used in a game of Keep on the Borderlands.
