I don't understand why one would spend so much time on this, then just smash it up. What a waste. If you didn't like it when finished, you could have put it up for sale. Even just getting a little bit for the piece would help for material cost for you, and then make a gamer very happy to have a nice piece of terrain to use in games. If you don't care about any money at all, you could have even donated it to a local game store where they host games, I'm sure they would have been thrilled.
