I did this for my Drawing for Sequential art class. The original is 10" wide. I used a .3 technical pencil to get the details.
I should reveal that I did a thumbnail at that same size and when I felt comfortable with it, traced the big shapes to make sure the perspective was somewhat ok. There are still issues, but I don't have the experience yet to figure all that out in a timely manner. At this point if I can trick most people then I feel ok, but the goal is to be accurate in every way.
I'm amazed at how well it turned out considering how busy and then on top of that how bad I felt due to allergic inanity.
