they have dwarves goblins, "scifi marines"...shoulder pads are really nice
as far as heads they have temple heads, what I am using, egyptian heads, and elven temple heads, and a crap ton of base inserts
next step in the pic brigade a test of water for the bottom. I am not going to flock the water area of the base because I want it to look deep so what I will do is just paint it blue then paint a coat of realisitc water on it.
here are some 40k bases to test
left is necron abyss right is mordian blue middle is necron abis with certain shalower parts mordian blue.
if I did it this way I was planning on painting the shallower areas as a sortof outline around the rocks and the head and maybe ad some water effects mixed with white for splashes.
