good start but you are rushing this car. there are some errors on the mesh for example the part where the wheel goes doesnt look round enough.
ru modelling from blueprints? and you will need a lot of ref images for this car. oh yea which model are you doing the f1 gtr or the f1 gt?


EDIT: I found a site for the car here you go https://www.conceptcarz.com/vehicle/z...1/default.aspx
