My most time-consuming project is worth to be the one for proficiency in Illustrator. It is a future Fuel Vapor car of Future Technology. To draw this car, to broke it into several pieces like lights, wheels, windows, window frame, and so on. With each part, I drew tiny shapes that I could see. Then, using gradient mesh to color it. First, it was really confused, then I found out how to use it. I spent a lot of time on the light and the wheel. After this project, from never touching Illustrator before, my pen tool and gradient mesh skills were improved a lot. I keep everything the same because it didn't look better than it is now.
