Thanx Michael for nice feedbacks.As I mentioned in my post,at first I followed my image reference,it was slow progress for me so I decide it to create separate file.Then I let it my mind create freely without sense for precision.I just focused on design and played with tools with trials and errors,and see what will come out of it.The main aim of this practice was to see,how I will create a real supercar concept for my client.They need from me to build it in 3dm or igs format,so I will give my best and build it with moi3d.Right now I'm watching some tutorials and modeling technics here on forum,to speed up my workflow,and I found nice tips and tricks.Until now I just tried to create some car models,but never finish it.Mostly focused on mobile phone devices and other more simplier products.This supercar project will be a huge challenge for me,and my big chance to design my own supercar.Automotive design passion is the main reason why I invested in moi3d,sketchbook pro and graphic tablet.As soon as I come up with some interesting ideas,I will post it on this forum.On link below there are some simple car toys I made with moi3d.
