Looking through most of the Earth Colossus entries again, while a lot of them are very esthetically pleasing to the eye, some are just unrealistic in terms of how you would fight them in game. And I think that's where yours is truly a winner.
Have you played Shadow of the Colossus? Your entry kinda reminds me of this guy --> [link]
If you haven't played, then that image will mean nothing to you haha.
