Forgive me as I'm big on aesthetics and an avid LOTR fan so Im very picky. Overall of course great concept as helms deep is one of my favorite maps to see in halo as it plays well with assault. You have a good layout down, however I would like to see more detail. As it is, it looks a little empty and as we see from the movies the whole keep is supposed to feel gritty and weathered. I feel that you could take some more time to iron out the aesthetics to match the movie more, i.e. The tower doesn't quite look right (more dome like on top) and maybe add more rocks or decals to spice it up. Also, again focusing on the movie, there were no catapults or siege towers so that seems out of place. Maybe you could script in ladders to spawn at a certain time like in the movie or possibly make a simple Orc-like structure where you want the orcs to spawn instead of the siege tower look. again, overall good look, I just would like to see more details that match the movie as this is one of my favorite franchises of all time.
