Here's my drawing of the Ferrari 599 GTB HGTE
I only had 1 colour promarker (ruby) that resembled red, so that's all I used in this drawing
Tools: Promarker, pencils from 3H to 3B, kneadable eraser, blending stump, colour pencils (faber-castell)
Time taken: ~9 hours
Tips and comments are greatly appreciated! So comment!
