Not feeling the back - kind of looks like the TechArt kit for the Boxster/Cayman.

I like the front, but feel like it would look better with the carbon gills body-matched. It might be cool to see the whole kit body-matched too. The carbon bits make it look a little too boy-racer.

 

Not sure how I feel about making the 360 look more like a 458.
As for how it looks, no complaints there. It looks nice.
I bet it costs quite a bit but people who buy these cars should be able to handle it.
