fist - You’re still doing an excellent job on this cockpit. If I can’t get concepts to you in time, go ahead and take a few liberties with the design and I’ll let you know if there’s something that I don’t like. You’re doing great! 
There are a few things that I think we can change right now though (see image below). First the leading edge of the console (red line) would probably fit the retro design better if it was consistent through the curve. You have it parallel to the bottom edge as it moves out from the center console. Try and keep the ‘V’ shape (green) all the way around.
The handgrips (light blue) can be shortened up some. Remember that our pilot alien has some really long arms so we’re going to have to make some space for him. Also, move the entire steering wheel closer to the console (purple) after shortening up the grips.
The seats look pretty good, but I still don’t like the design and haven’t come up with anything better yet. These seats are the only object in the cockpit that aren’t rounded and curved. They look out of place. Anyway, you did a good job interpreting the design. The side restraints could be angled out more and the bottom seat portion shortened (yellow) but I wouldn’t work them too much as I may end up removing them anyway.
