Water Horses. Either to be used as an over the top marker for some sort of magic thingie or spawn, or (unlikely) to be used as a unit in itself. Unlikely because I am not that happy with how it turned out, but it was a good lesson. Version two will likely look better. The bright colour scheme is due to the fact I tried to tie into my High Elf army, which is all about gold and blue. Bright.
EDIT: Forgot the normal disclaimer about it not being all finished visavi the painting (namely the small rocks at the bottom of the angry creek).
