There's something I can't determine based on these images, does the space between the hull and pylons have a plug? It's something I think I didn't see on the modified Miranda from the update. I have a picture of the Miranda model with plugs filling the gaps between hull and pylon. I think I see the difference, on yours the pylons are straight up and down, but the model has the pylons angled outward as they go down, then go straight down once they reach the bottom of the hull. In the right sub-image, we can see a vertical ray in the plug that helps us see the angle of pylon and hull. This explains why the gap at the top is too wide and too narrow at the bottom.
We can also there are details inside the upside down triangles on either side of the shuttle bays, they have lights in the center and base and three rays extending from the larger light.
The torpedo pod also seems different from yours. Your model has the two fins in the tail extension reach the entire length of the groove, but the physical model has the two fins extend about half the length of the groove. I think the physical model's tail extends back further and may be thicker in circumference, the fins may also be slightly thinner but that's hard to tell.
originalBelow we can see how the pylon is angled from the side. The top and bottom do not penetrate through the same vertical line, the top is offset inward about 1 or 2 degrees, considering the edge of the hull also slopes outward as it rises. Without that angle of the hull, the angle of the pylon appears greater.
