That looks pretty spot-on to me DB...
If anything's maybe off, it's the diameter of the cockpit ball itself, but it's so old and Hasbro seems so content with it... I'd say it's a negligible difference too, personally. It doesn't look much different to me at all, but for the small details like the laser nub, and cockpit hinges, etc. Like I say, maybe a hair larger diameter? Not enough, to me anyway, to worry about... And I'm a stickler for this stuff generally.
I think more people are annoyed by the cockpit hatch hinges honestly, though I'm again not bothered by them myself... I see where folks come from on that issue though.
To be honest, the difference I see with the cockpit is more that the model is a hair more oblong than the toy... Which makes sense due to the way a pilot should sit (knees bent) in one. Again, I think the wings are spot-on accurate, and the cockpit ball maybe is off by the slightest of margins...
At this point though, they've retooled the cockpit ball so much that I highly doubt they start it from scratch to make it that slightly bit more oblong to accomodate a more natural sitting position for a human. I think the Kenner styled cockpit ball is here to stay... But the scale of the ship is right on itself, and lines up with the TIE Bomber, Interceptor, and Advanced x1 pretty perfectly. If the wings were 80% their current size, that would make the ship FX X-Wing scaled actually.
