Yay cool hi5 blender pal!
Yea you know its a pitty that for a general cool modeling
some details like the low contrast on wheel drawings, lights and windshields
they are just spoiling the scale sensation that gives that toy look, wich in my case i didn't have at first glace until i could look into those details.
(when people make scaled modeling in real life the great deal after getting the cool overall proportions is to give the acurate details that will ensure a real scale perception)
But great job, if you have been able to do this it will be easy to get over those little problems on further car modelings
