Yup, I am with Arch, you could have worked a little bit more on the skin, now it looks a bit like soaked in that brown wash. To improve the effect, you can go with that brown wash and insist on the deepest areas only. Then you could work on the highlights mixing that pale green with a dab of pale yellow and applying it only on the more exposed areas.
I also see that you have mixed blood for the god and that other green slime thing... the problem is that the green slime thingy has almost the same colour than the skin so it looks a bit strange. Anyway it's a "discusting nurgley" work so keep on it! ;)
Try that green slime on the recesses between the intestines instead... I think you would get a more striking effect.
The skin looks great - a few brighter highlights on some of the boils and on the intestines would've made it a bit more striking. The big armour plates look nice and corroded. It's a pity about the large join line running down under his left arm.
Overall a good job on a gleefully disgusting figure. :)
