Looking pretty good so far jsprogg...

But theres a view things that are slightly amiss....

The front air intakes on the hood do not match the reference image you posted, also the air intake strip that runs along the length of the hood (on the top and sides) seems to be slightly off shape. Maybe they should be thiner at the front.

Also, the front of the rear Fender (Where you can see the horizontal intakes) needs to be thicker and broader. Expanding the width of the Rear wheel well/Fender.

Also the area along the side of the car in between the front Wheel well, and the rear. Needs to be allot less pronounced (perhaps get rid of the crease) and it also needs to be more rounded, and smooth.... maybe even slightly thicker even.

Also the the front corner of the hood needs to be even more rounded.

The rear wheel well seems to be a bit close to the body of the car.... maybe this is just the image that I'm looking at...

Also the underside of the front of the car needs to be brought down.... on your model the underside tucks up under the front. If you look at the reference you'll see that it actually flows down as it gradually flows back under the front.

Well, I'm sorry if it seems like I'm trying to dismantle your model, but I'm just pointing out a few little problem. Most of which can be fixed with very little effort.

Also one more thing.. try and find as many refs as you can for the car your going to model.... Though I'm sure someone with as much experience as you might find this statement offensive especially coming from a noob!!! But I've seen way to many people try to model a car (or anything else for that matter) with only one reference image.

One other thing... i know that the renders you are doing are just quick no time spent on them renders, but the paint shader you are using for your car is extremely off!
As you can see in the ref, this car has been painted with the old style paint.... which is more of a thick acrylic glossy type of paint..... the paint you are using is thin and full of paint flakes.... Though again i know this is just a quick set up simply to show off the modeling.

Also i find it better to post Clay renders as this shows of the model at it's purest form.... and all the details are clear, and people can make better judgment on the model.
With a glossy paint, it can be hard to see any problems in the mesh.

AGAIN!!! I'm sorry if this all sounds rude and evil!!!

I'm a noob at modeling, and at Cars in general. And i enjoy seeing good artist model awesome cars, as it inspires me to stay in the game, ... and this one is one of the most awesome cars I've seen someone model...
So I'm just trying to help out anyway i can.

Nice work so far, and I'm looking forward to updates!!!
