they look good for tabletop quality but i would paint the sand to. now it looks really fake.yes i know its real sand, but using real rocks and such look fake to. maybe you should give it a black undercoat and then work it out to some brownish sand.
I like the conversion on Kroq-Gar. Not sure about the mage priest yet. The colour scheme is good but what are the things like cuts on his eyes.
The kroq'gar model comes with a shield, which is confusing because he has no option to take one. Also, nice slann, but I think you should paint the horns on his chair a little more, they look weird stark white.
very finely done at a diffrent qrok gar pointing spear upvard and having shield though sadly only for show
