Troll vomit

So, my Son gets these three Trolls for his army, chooses what shade of greens he wants them - then promptly hands them over to me to do them for him. Happy to it of course and it made a nice change to gloss everything as they're River Trolls and my Son wants them to look like they've just crawled out the water. Another challenge was - how do you paint vomit? These beasties have the charming ability to chuck up on thier enemies and one of them is in mid-chunder. But, how do i go about it? Figured it'd have to be a creamy sort of affair, so what i did was to build up from a flesh tone, highlighting with ivory then washes of brown and orange inks, go back to the flesh tone and starting all over again. And just build it up that way - with copious coats of Gloss varnish to finish off.
