Hi Elang,

pretty nice modeling you did there! if you allow me one small remark, it has to do with the "seams" of the mini: the metal plates of the mini bodywork were welded with the seams on the outside, unlike all other cars at that time, to keep production costs low. So there were 2 thin flat rims sticking out, and point welded together. it is very hard to see on pictures, but it is not a round tube as you modeled.
here is an example where it is more or less visible when you zoom in:

or even better here:

there were no rims around the doors.

hope this helps!
