This car looks a lot better than your last try. and the focus of your issues moved a bit.
You also added alreay some nice details, like the door handles.
It looks rather good as a whole, but if you compare it more in detail with the reference a lot of detail issues appear.
You have by far less jaggies in the sprite, however some inconsistent lines can be found over the whole sprite, try to get rid of them. Also at the bottom it doesn't really make sense that you don't use a straight line there.
The other big problem you have is banding. nearly all areas around the windows, the bottom line and the line above and at some other places the sprite suffers heavily from it.
And because those are both sprites for the same game, you should be consistent with some details, like the transparency/lighting of the windows. Use the same colors/technique like in the last sprite, to achieve a style.
I am not confident about the tonal alues of the yellows, the contrast could be a bit higher, to emphasize the metallic effect.
In detail there are quite some planes which are off in their angles, i filled up some of these areas with red in your sprite.
You also don't added the front windscreen, which could add a lot if it'd be there.
the magenta area is heavily off in proportions
the blue areas could need some work for detailling
at the top of the cyan area you can see a disconnected line, this looks strange.
The area you pointed out looks imo like a conical panel, or at least I'd shade it like this. The light gray areas there look indeed strange. Is the reference a photo or a 3d render? I suppose it's a render and 3D programs aren't as exact with lighting like nature a photo is a much bette rreference for tonal relationships.
