Here is one design I put together, Arya:
I did some tests using a tablet in the GIMP:
This made me think of another thing. As I was drawing it occurred to me that even if I were to make the switch from 3D to 2D, I'd still miss the ability to look at my concept in 3D. Knowing that every aspect of my design has perfect perspective and that all details are objects and not just dots drawn out of lazyness.
I may try some more 2D sketches, stylized ones like these. It may take some time though before I can actually get good results and actual proper proportions.
I leave you with this image of a very narrow-sighted scientist.
