FIRST OF ALL, DOWNLOAD IT TO GET THE FULL IMPRESSION OF THE PIECE!
(I' put in a lot of details)
My Rift Colossus entry:
Dethrant - Leviathan of the seas.
An enormous cephalopod, turtle, dragon, humanoid abomination from depths so deep it would weaken the heart of even the bravest!
I spent a whole lot of time, and even feared not making it within the deadline, so it is a rushed work.. as one can notice at several areas.
And for size comparison... there's a ship on it's shoulder, really way beyond the gameplay size for rift.. but if I am to make a colossus I make it colossal!
