'Syren' Sports Car Concept (3D, WIP) - Feedback wanted!

This exotic design is one of my latest projects. Before continuing to the next stage, some feedback (comments, questions) from the community would be very helpful.

P.S. If at all possible, specific and constructive comments are most useful, while comments like "this sucks" or "this is awesome" are of little use.

Your Conceptcar looks very interesting. Would be nice if there would be more details (LED head and rear lights, windowshapes etc.). It´s a Nurb-Model right?

it reminds me of something from supercar street racing. it looks cool but details would help.
