After much research and playing about, I have finally started a render of the Big Ben in Mars scene!
Created a matte painting of sorts of a Mars landscape using actual NASA images of Mars. Made it twice a long as required so I can move it a little in Motion or After Effects. It won't have any parallax doing it this way but seeing it's supposed to be a bad camera on top of a rover I think we can get away with it.
Once the render has completed - leaving it over night at least - going to add some real dust falling from parts of the Big Ben model, as well as some atmosphere etc to bring it to life.
It will need some colour correction as well - basically a more orange/warm colour and then some UI graphics and it should be done.
