this illustration took about 3 weeks, big chunk of that time is searching for all the 3d parts in NX and exporting.

In the old days to do an airbrush job would be a bout 4 weeks but this is 100% accurate, down to the last rivet if I wanted, although i usually strip out a lot of fixings in something this big. And the bonus is I can add extra bits if need - just remember the viewing angles and export at same size and position and it slots right in.
