looks like a good start.you want CC?you get it haha.
first the tyres stick to much out.the mirrors are to to small wrong shape.the headlights?doesent know this lamps exits.the side lines at the roof is missing.the hood at the front looks to flat,and doesent fit at the window,where the wiper should be.the downpart from the frontbumper looks pointy.the front part from the door,or the chassisframe doesent fit.the side from the real car is curved at the door.the B pillar from real cars arent flat,they are slightly curved outwards. hope this helps
