Cheers Cam.
It's always interesting to compare someone else's view of your work with your own view. With the vats I enjoyed the build, but really hated the painting, and that coloured my whole view of them. I also felt I could have done more to the them in with the walls, maybe some dripping flesh from the nozzles, or a piece of wall made that attached to them.
Good points on basing and variety.
Although there is a certain regularity required by the idea, I had put some touches in like the odd tentacle (obviously

) and hole, so there certainly was room for more of that.
Not sure I would have gone with decaying greenery, most of my basing is urban battlefield or rubble type terrain, but there was definitely room for more details and attention in the actual bases, maybe even basing the vats themselves.
