Well, I took a screenshot of AH's Spit XIV cockpit from as close to the same angle and distance as your closed cockpit shot to compare. Now I couldn't quite match the angle because I couldn't get close enough, but the armor section may be a little too thin when viewed from the side. On the other hand the framing at the front of the bubble may be a little too thick in AH.
It is pretty close in any case.
The closed shot you posted also has some unknown item attached to the inside of the cockpit under the mirror. I am not sure what it is, but it makes the visibility look worse than it is. Other Spit cockpit shots lack that thing, so it isn't something that should be there so far as I know.
