Looks fantastic!
But major factual errors(!!):
1. Nose gunner never sat like that. I have
never seen a seat mounted there, plus physically there is
no space to put the feet like that!
2. The Top Gunner, gun is
not fixed on the bar but pivots on it, so it would be loose and point straight up (due to weight of back end).
*if* the bar position was to rear, then the barrel would be pushed aft by the wind.
3. The DG radio antenna, the reddish object just in front of top gunner, is completely wrong shape.
