I like all. But autnum seems to be perfect in my opinion. 
it’s a spitfire mk.xvi, similar to the mk.ix but with a bubbletop cannopy and packard built v-1650 merlin engine, also one of the rarest late merlin spitfires
Nicely detailed and very impressive in its camera view! The spinning propeller too has been given very successfully… looking to the image someone almost hears the roaring of its engine! : - )
