Frank you really need to up your aircraft recognition skills!
For a start that is not a B17 tail, it's much much too small for a start, looks far more (to the point I'm certain about it) like it's another P47, to go with the nose in the background. Or it's one supersized Jug back there. The P47's are a little incongruous for an early war E series 109 to be flying over too. I think this P47D shows the fin/rudder configuration well enough.

Maybe not such a great photo compositionally, but it does demonstrate the shape of the fin/rudder better.

Then of course you have committed the greatest possible crime in the aircraft identification annals. It is sacrilege to miss identify a Hawker Hurricane as a Vickers Supermarine Spitfire. The aircraft in your photo being either a Mk II or a Mk XII. The Mk XII simply being a Canadian built Mk II. You can instantly tell a Hurricane from a Spitfire in a nose on shot from the large centrally mounted radiator fairing, a much thicker wing section, and the fact that the main eight .303 Browning machine guns are in a close group of four in each wing. RAF practice was to have a red cloth patch fitted over the guns to prevent icing. On the Hurricane this is seen as a large single "block" of colour on the leading edge. The Spitfire has a much thinner almost laminar flow wing section, and the 8 Browning's of the early marks are mounted signly in the wings, with four individual small squares of red. You can tell it's a Mk II/XII from the fact that it has two extra guns mounted outboard of the landing lights, bringing the total to 12! A Hurricane of this type would not have been out of place doing ground support in the Tunis campaign although this aircraft is not fitted with the underwing bomb racks of the Mk IIb variant.
A Mk II closest to the camera, with a Mk I behind. The Mk II is actually in the markings of a 1940 vintage Mk I of the Battle of Britain period, and both aircraft were flown by Polish members of the RAF. They have removed the outboard guns in this plane. The RAF's Hurricanes not only shot down more bombers than Spitfires did, but they also shot down more fighters too! But then we did have a lot more of them, as they were more traditional in construction than a Spitfire, and so easier to build.

This is a MK IIb, showing the bomb racks fitted under the wings, and the protruding muzzles of the outboard guns.

The Mk IIc cannon armed version was often used for ground support, fitted with four 20mm cannons. They even had one Hurricane version fitted with 40mm cannons for anti-tank use in the western desert campaign operated by No 6 Sqn RAF, still known as the Flying Can Openers.
Here is a Spitfire Mk I that was shot down over France during the Dunkirk operation. It then spent 50 years buried in the beach at Sangatte before a painstaking restoration to flying condition.

When it comes to compositions I usually try to get the aircraft from a more interesting angle. Although dead side on shots do have their place, especially during takeoff, when the gear is part way through the retraction cycle.
Prop blur is really important IMO, and even harder is rotor blur for helicopters. Large helicopters need really slow shutter speeds, I used to find 1/80s or slower for the Sea King, and needed 1/25s for this RAF CH47. Oh and it really helps if you are blessed with good light. Too often at shows the light can be really bad.
I might as well throw this one in to fill up the eight photos.
