It is just lighting changes and adjustments to get the materials to show better. Early on I had a NO NO tinted light as the main. I converted to the light rig from the IOWA thing to neutralize the WIP renders so color is represented in a neutral way. Part of the orangey light was leftovers from the SOTL render set up.

Unlike many of my TNG ships this one has a much stronger Galaxy egg blue color to it.

For the deflector/ weapons areas I was considering having it in that flat face of the cutout. Or to cut flat across the top some where and drop it down ( I think this is what you are suggesting.) It can be flat faced or curved following the hull. Sampled follow the curvature. I am thinking #2 one is the way to go as it provides enough size for the things I might add. Though nothing says I need to do a secondary deflector.
