Titanic - Machinima Possiblity?

So just some early shots from a Machinima i'm thinking of doing. Trying to recreate the Titanic film - its definitely a lot more difficult due to world and build restrictions compared to when I did it for Sims 3. If anyone has any tips lemme know. Also I havent bothered turning off headline effects jsut yet - Im still set building - these shots were just for fun.
