Quick paint on a pair of orcs from Scotia Grendel (formerly by Black Tree's LotR range) to see how they compare to some of the other figures I've got. Both are leaders from the command packs. On the left is a Greater Orc (Uruk) on a 25mm base. On right is a Stygian Orc on a 20mm base.

Second pic is a comparison... Citadel plastic handgunner (my usual scale standard 😉), Reaper, Scotia Grendel, Midlam, Grenadier/Mirliton, Black Tree, really old Citadel, and Scotia Grendel.
