@ flm: OMG ... I never imagined that you would't believe it's drawn by hand, without a trace. :( I specifically uploaded the image showing the vectors in the Outline mode. No trace of this can't be achieved. I tried to do a trace - that's what happened . This is the best result. :? This is not such ...

flm, Of course. I drew it in this picture (but it was smaller). You can compare the original photo and my work. I can send you the my SVG source

It's an Audi with the wheels of Porsche =)

Тhanks dude!
Тhis is my another work: http://jumpordie.deviantart.com/art/Alarm-193665588
I'm new to vector graphics, so these reviews I was very flattering. I'll continue to improve my Inkscape skills.

Done exclusively with vectors and by hand entirely (no tracing involved).
