On the left is a stand of Splintered Light Dwarves, from the "Splintered Lands" line of miniatures. As you can see they're a bit big and would probably fit better with true 25mm. Still great miniatures in their own right!.
The middle is a stand of Black Raven Foundry's Wraiths and on the right are Splintered Light's orcs. The orcs are the "Heavy Hitters" and one command figure. These are actually a bit larger than the rank and file orcs.
The left side is a stand of Splintered Light's Arthuran Wolftail warriors and on the right is an Arthurian Warlord.
The figure on the right is an old plastic 1/72 (I think Airfix) barbarian. I really think the classic 1/72 range which run from 20mm - 24mm are the best size fit for the Black Raven Miniatures.
Hope this helps anyone look at any of these ranges.
