I have no more time to put into this, so I’m calling it done!
The reflections are done via a jpeg mapped to the horizon. The lighting is 3 lamps, and the AO is set at 11 samples (it’s set on both also). I did some radiosity for the stuff inside the engine (still don’t know what to call it).
I wanted to keep this design simple (as you can see), so I hope you all like it!
