I have been drawing the 2D sides of cars since i was 11, and only just the sides. Not the front, back, or 3D drawings, just 2D flat drawings of the profile of cars. I have kept my drawings from the age of 11 till now and i have improved drastically from then but still am just drawing the sides. Should I go about doing 3D practice drawings or consider something else? I will not be heart broken if anyone says I suck, I can easily go into architecture and/or development, so I am not banking on any one thing. Here is a recent drawing of four cars below:
Thanks for your answers!
