WoW -- thanks for the advice -- it is always welcome (if not always heeded

)
I didn't mean for the renderings to look particularly sharp, and don't think they are too unrealistic.
Look at the 1M coupe (of which I got some obvious inspiration) -- it has similarly "sharp looking" elements (well, at least that is what I was trying to illustrate):
While I usually always do more simple and clean stuff, I wanted to do something a bit different here -- more overtly complex and "layered" to try and give it a more "technical" feel. To try and stretch my style a bit. Plus, I felt this car needed something a bit "busy", since the stock bumper is soooo traditional.
I know it isn't for everyone. Heck, it might not be for anyone--it just sort of "came out" this way, and I liked it, so I posted it.
In the end, most people will want to make the car look like a Supra, or the GT350 car, or more like an AE-86, or something else they feel emotionally connected to. Heck, most won't buy anything more than an add-on lip kit. Those would be more "economically viable" design options. But, that isn't what I was going for here (obviously

)
That is the beauty of digital artwork though -- it is incredibly cheap to do, and no machinery gets hurt in the process
