Div ... the 3rd NSX looks great ... very realistic
but I think you are overdone the blur job on the reflection
or maybe it is an artistic brush creation (need more detail on the reflection)
anyhow ... I like your BMW shot
The red Bimmer on the Nurb is a good shot, except....I can't seem to put my finger on it... looks like you sharpened it too much or something. Also the BMW Power signs are so crappy compared to the rest of the image that it doesn't look real. Otherwise it would be really sweet.
