My vintage motorsport artwork

Vic, as a fellow ‘artist’ and I use the term very loosely where I am concerned, I am still in awe of your work and am trying to get my head around how you do it. I haven’t drawn for a while and am currently practicing drawing a mk1 golf, but I am struggling!

What is the process you go through when doing a drawing and what products you use. I know you have said you use a combination of paint, crayon and graphite, but what do you use in each process? and what type of paint/crayon etc as I’m sure you don’t use crayolas finest:)

I don’t really want to sully your thread with another of my drawings as to me at the moment it looks like something a child has drawn but wonder if you think it can be saved!
