The muzzle flash one the Spits were huge, but this is WIP, I know
The propeller dynamics were great, and pretty smooth. It's also nice to see little puffs of dust, paint, and metal flakes coming off the Dornier's skin when hit by the .303s.
And let's talk about the opening shot! Wow!! The detail of humans is top notch, and from a good eye level perspective, giving a nice sense of scale. Evening lighting looks great as well.
This especially caught my eye:
From here it looks like we are no longer seeing the old 2-D fire balls. And just look at how far the smoke stays suspended in the air! Also take note of the offset camera angle: In Il-2 the Bf-109 would take the center of the frame.
Great update! To me it looks like it's nearly ready.
