2006 Ferrari GTB Fiorano

This is the 3rd photoshop render I have attempted....As the name would imply...it is of a 2006 Ferrario 599 gtb fiorano....It is such a beautiful car that I knew right away I wanted to try and render it....This time I went into a whole lot more detail than I had the won-tons to attempt on my first 2 renders. I actually did the rims and headlights this time....the rims took me about 1.5hours....about the same for the headlight.....all said and told I probably spent about 8 or so hours doing this car. I think it turned out pretty good....but please, let me know what you think of it. If any of the more experienced people out there have any ideas on how I could improve this then please let me know.

thanks!
