Okay so you want some constructive comments, here they come.
1) Once again I tell you that the Castrol logo down the side is horizontal and fits across the car, not slanted and does not fit (like yours).
2) Windscreen strip on the window is not green it's red, and I can't tell you what logo it has because I do not own GT.
3) You're missing multiple ads around the car incase you plan on finishing.
4) Fix where you have FTO on the wing, make it slant with the top of the wing, and decrease its size.
