Treasure model sucks use a good treasure like this
http://www.wc3c.net/showthread.php?t=82692. Also I don't like how there is no moss or overgrowth on the side of the boat why just the top that thing should be covered in greens!!!! The next thing is add more holes if it was a ship battle or ran into something there would be more holes and add some debris on the side??? Sunken ships are homes to a lot of fish life such as sharks, eals, fish, etc not just jellyfish so add more of those. One big thing I don't like is the nothing in the back I know it's underwater but I feel like if you add some awesome it the back it will make this terrain epic. Ship also needs more detail like maybe some cannons or barrels and stuff and maybe a skeleton or 2 lying around??? These are all I can think of right now will add more if I think of some.
