That's so true a pilot body is a must and this will give even more immersion! But I think is work in progress. The size and scale of the cockpit in my opinion is great.
The HUD it looks very ok for me but the MFD's are hard to read, not so dramatic the mfd buttons, but to lock a flying target I need to zoom 100%, not easy when you are preparing to engage. (Oculus Rift S)
Without VR I would say its on the limit to read the mfd's.
Here is an interesting video of the mfd's brightness irl (the go pro though its a bit higher from pilots eyes):
in the 3:27 of the video its clearly bright enough to see the targets in the air.
