The whole piece looks in terrific!
I agree with Ten Ball that maybe those electric greens on the moss could stand toning down a bit. Under a dense canopy, I would expect the light on the forest floor to be pretty choppy (which isn't to say it would be uniformly dim).
I like the spittle. The juxtaposition of elaborate, slightly fussy gold armor (I mean, that hat?) and pure, slobbering, bestial rage is delicious.
I also love the detail on the brass foliage. It looks great.
Again, wonderful job and thanks for sharing.
