As for your rat ogres, I'd suggest adding a slight highlight to the green cable on the one with the fist spike; it will help tie the green in to the other Warpstone colours you've used.
The Cable was interesting for me because I do usually highlight everything but when I painted this I was like "Im just going for the flat green" very strange indeed... Just felt like I had to leave it at that. It does have some darker elements to it, only a little, but the camera pic doesnt show it.
Thanks for all the comments
