Good stuff Don.
The PE bomb bay doors alone are worth their weight in gold - it's the scratch-building of the internal frames on the doors which has delayed me finishing my model. Such resin and PE parts weren't around when I built the model.
On mine, I opened the bulkhead doors at either end of the bomb bay, and the radio room door into the waist area, as well as the entrance to the nose compartment, and opened both crew entry hatches.
With the bomb doors open, and empty bomb racks, this allows more light into the interior, and at least some of the added details can be seen, both through the various windows and hatches, and through the bomb bay if the model is viewed from underneath.
The slight 'downside' on my model is the lack of colour contrast in the interior - later 'G' models had clear-lacquered alloy walls, no paint or primer, except on bulkhead frames, so it looks a bit bare in places, although the painted areas, and the 'wooden' tables and nose compartment floor, do give some highlight.
