Stirrups and a bridle! It's the little nods to realism like this that set your work a cut above imo. And the aforementioned skin tones, of course.
Thanks! I also thought about making some reins to steer the squig, but the grot looks too weedy to actually pull hard enough to make a difference.
Speakin of skin tones, have you checked this out? http://www.the-waaag...showtopic=49653
I paint the grotz basically the same way, only starting with a lighter base colour, Knarloc green at the moment.
