Do you do this for a living? If not then you really should. Your work shows great detail and would look great in any magazine. I admire your ability to draw vehicles so well. I have an incredibly hard time with them. I have a couple of pictures of my son next to our blade and tractor and the only thing that holds me back is the fear of having to draw the big machines. You have a lot of talent.
Thanks for the compliment. The pics are laughable.
Machines are easy. Perhaps it's my old drafting background. I don't know from CAD; I'm old skool pen & pencil, triangle and compass. It's the human form that makes me struggle. That's when I just wing it and go with the flow, whatever that is.
