Spitfire Low-poly 3D model

This is a my model Spitfire mk1 as flown in the Battle of Britain. I've tried to keep it as low poly as I could 21099k in total and the topology is fairly good to. I have rigged the control surfaces, landing gear, canopy and door and all seem to work fine. I have also added shape keys in as well. The textures are all 4k and in tiff format. The Mk I was built with a Merlin II or Merlin III engine giving it up to 1,030 horsepower. This gave the Spitfire Mk I a top speed of 362mph at 18,5000ft, making this model faster than existing British fighter planes such as the Hurricane. From June 1940, thirty of the aircraft were equipped with twin 20mm cannons.
