i'm looking for suggestions on how to make a cake of the titanic (before it sunk) thanks!

Hi
I made a titanic not as good as I have seen but customer loved it.

I used a 10" sq sponge, cut in half and put one half on top of the other then carved into ship shape putting some of the off cuts on top to shape the top of the cake.
Covered bottom with black, white with top, then added little black squares for windows.
Made 4 funnels out of RKT and covered with yellow mixed with a hint of red then black tops stuck these on top, made an iceberg from RKT and there you go
