Synth, I really do think your car is pretty much perfect. The vented hood, and front lip will not make your car look better at all. Both of those items make an NSX look aggressive at the cost of clean lines. With your car's color, it caters to a cleaner, simpler look. A front lip will drop the bottom line of the nose lower, making the OEM side skirts look too short. If you now have to put skirts because of the lip, then it certainly starts moving away from what you are trying to achieve. The R hood could be done, but again, its an aggressive look instead of a clean one.
I do agree with one thing though, the TE37s looked fantastic. I don't like TE37s (blasphemy!), but yours is the only car I ever said, "that looks right."
