That video looks great! (Spitfire in the Clouds). Despite the nasty artifacting from youtube compression, it looks absolutely teriffic.

Compare it to the british map of Wings of Prey for example. Look near the end where it manuvers a bit and pulls up towards the water where there's tons of sun reflections done very nicely in the water. It's bright, but it's not exagerrated as the Wings of Prey style was.

The shadows in the cockpit look very sharp and appear to be complete and covering nicely.

The instruments moving looks very nice as well. Note the unstable nature of them when throwing the plane around (I recommend reading how mechanical measurement instruments from the era worked, and still do today to some extent. Fascinatingly simple yet effective).

It all looks very, very real to me. Maybe I should look into getting a second 9800GTX+ to be able to run it (SLI.. poor man's upgrade).

I also think the colour shade of the water as well as sky in particular looks superbly convincing. Water has some foaming on the top of waves (I know 'perfect' water in IL-2 has much of this as well) which gives some references to gauge your speed/angle compared to more flat lifeless waters.

EDIT: Comment on the G-forces and head movement - for being a fixed view mode, I can't imagine what could be done to make it better. I'm not sure in real life how much you can keep your head centered behind the gunsight display, but I doubt you can if you are doing sudden violent moves. The delay/lag simulates a neck pretty well.
