I decided my Orc army for This One's Split (http://thisonesplit.blogspot.com) needs a few big dudes. I liked the Games Workshop Lord of the Rings Isengard troll, so went for that figure. It will do quite nicely as a giant in 15mm scale. I've put a 15mm demonworld orc next to him for size comparison.
Started today and I did the base colours and wash, and a first highlight of the metal and the skin. Overall I like the way the figure is starting to work out. Need to pay close attention to keeping it stylistically close enough to the 15mm army though.
Planning to have at least one of those finished for the demo at Action 2009, Rheindahlen.
