Dave,
Overall the cockpit is looking very nice. Since you mention you're trying to get a model level of accuracy to the level of the original, here's a few things to keep an eye out that aren't quite right or missing details from the original on yours, but you are certainly on track and getting close in most areas of the cockpit.
Can't tell for sure due to lack of focus, did you use the headlight from the Morgan kit where the largest yellow circle is on the back port panel (see ref pic below, you can easily match the raised details to the headlight) - maybe it's just the background glue that obstructs the detail.
The 2 vent parts cut from the Morgan looks nice how you approached it, but those parts are too 'thick' compared to the actual armor kit part used there, which was not the Morgan but you've made a good substitute. I'd try to at least shave those down so they are not as tall as they currently are.
The area though that is missing quite a few details from the original is the back upper black control panel, there are a number of missing white 'cutout details' on the outer parts (edges) on both sides - what you have looks great really, but not quite accurate if you are trying to make the replica match the original. Not sure if you accidently painted over them, or maybe just didn't include those details (easy to overlook due to shadows in most refs)
Your fan is sitting too close to the back wall, you'll notice in ref pics it sits back farther, that's because it used the KoolShade vents in addition to the window to pull in the airflow and you don't see the blades so obviously with the correct set back, definitely recommend moving that back at least so you aren't seeing the shadows of the blade so close to the wall.
Assuming you will still be adding the orange coloring in some of the round openings on the Hurricane part on the back wall (all of yours are white right now)
The part just to the left of the 'clock' part on original protrudes out almost 3x what yours is (also ref the pic below of the yellow headlight, and you can see the 'pyramid' part protruding, where yours is just a little short block.
The Stug parts appears a little too far away from hurricane part (notice on original, aligns with the middle rib of the armor part (your Morgan cut part which is slightly oversized than actual kit part), on yours it's farther out and it should 'nest' under the armor part.
The center console as looking head on from should be tapered, not square. (ref pic below)
There are other little details for the cockpit that are missing - but I'm sure no one will really notice except the very few 'die hards' - so you are doing really quite well with what you have done here! Nice job.
In the end, no one will have an 'exact' replica, but we sure have fun along the way trying!
