One thing to correct: remove the flat top. The dome should be continuous with no flat area — it curves all the way to the apex. Any flat platform visible in period photographs is a later addition (a gun mounting) and is not part of the original shield shape.
Profile corrections by zone:
Sides (middle three sections): These are the rolled plate panels that wrap over the gun. From the side they appear as sheet metal bent in a relatively gentle arc. The profile here is not as steep/aggressive as shown in the current model.
Front face: More strongly rounded, softer curve — a fuller, more "inflated" look when seen from the front. The transition point where the front face begins to flatten into the side panels is marked approximately by the blue line in my annotated reference image.
Rear face: More squared off and upright, almost vertical when viewed from the side. The rear curves less and drops more steeply — almost a blunt stern shape compared to the bow-like front. This is where the opening is for crew to enter the barbette/shield.
Steepness of sides overall: The sides in the current render are too steep / the whole form is too compressed vertically. My model photos show the correct proportional height — the shield sits inside the barbette ring, not flush with its outer edge.The edge is very small of course.
Reference earlier: The painting of Vauban is a reliable close reference — the shields on that ship were nearly identical to Turenne with only minor variation. You can use it for surface detail and curvature confirmation.
What is correct in the current render: The gun aperture shape and position reads well. The overall plan footprint (as seen from above) is in the right ballpark.
Those are my observations of course, I have been staring at this forever and have figured out how to make it in my head and using just putty on the model. However it is far from perfect, lacks any possible texturing but may be thats ok in that scale. Agree, the Kit is horrendous in execution of the turret shields.
Hope this is somewhat helpful?
