i think the blur looks foggy, not like a crisp reflection. i think the composition is awesome and for 3 hrs it came out well.

I think the nature of new shiny cars do not have only blurring effect on the surfaces. It leads to the idea of dullness and dusty. How about adding spots of sharp reflections here and there. I think you would find more use of the gradient tool with degrees of colors and also many uses of the blending modes and opacity. There are always two lines between the body panels, one is darker and the other is lighter so we can see the reflections. I think the headlight has got well rendering. You can add another layer of gradient on it as a sheet of reflection. Sometimes the solid hilite spots give stronger effect than the blurred ones. Also consider final look as well for which to decide on the background. It should relate to the tinting degree of the transparent objects like windows. I see that the shadow is red, that gives the effect of the car is translucent. I think you did real well for the three hour job. I did mine in periodical sessions before my eyes gone busted and had time to criticize my direction before I simplify my goals. I hope my honest comments serve you as you requested personally, and I found this is one way to reply to you. I hope I do not offend you or embarass you. You should see my first work, no you should not ha ha..
I thank you for your compliments.

I think the subject matter of the piece is great, especially with the fisheye lens effect. However, you could have finished with a more stylized look by leaving the blur effects out completely. Overall, great job for 3 hours!

I agree
