I wasn't gonna post the finished picture of this till after the contest but the "judge" popped by my house and saw it anyway, so I might as well.
This is my conversion of a tzeentch herald on chariot of tzeentch. I'm hoping to get some better pictures done at some point, but for now i'm happy with the result. The horror wasn't too bad, but getting the tails to stick on those screamers was a real chore. In the end I had to flesh them out with green stuff to a) keep them in place and b) cover the gap where the two parts didn't quite meet. At 20 quid for 3 you somehow expect better, especially when the plastics are so top notch.
