What Karl said !
Great work on the cockpit Vic, and I like the Sutton harness, very nice ! Is it too late to get rid of that shelf thingy behind the bulkhead? It shouldn't be there, ( sorry, I didn't spot if before). The area was open, with the main (twin) oxygen cylinders vertical on the port wall, and the black, feed oxygen cylinder (horizontal) on the starboard wall.
To be honest, in this scale, it's difficult to see anything in that area, and especially if the canopy is open, so just removing the shelf and painting the whole area Cockpit Grey Green would be enough.
