Thanks
The steps:
1: The scetch is made with a ball point pen
2: I scanned it, took it into Adobe Photoshop and changed the colors to black and white.
3: Made a new white layer with some opacity on. And started to fix up some of the perspective with the "polygon help lines"
4: Started tracing it with a generic brush.
5: Just tested out some colors, not important, since its not going to be used.
