Very nice, I did notice the canopy but nothing to add that hasn't already been said.
The wear and tear on the engine is a very good shout.
The Stuka received a lot of attention from our Hurricanes and Spitfires and once Goerring ordered repeated Sorties into Britain mechanics worked endlessly to service and repair them so a lot of cowling/engine/frame banging ensued.
I usually research the aircraft and look for decent pictures for reference.
