Id say drawing is part talent and part hard work from my stand point on it.
I can draw pretty well, not like chip foose, but still not to bad. Im from more of a creative family, such as my mom was well known around our area from her painting on arts and crafts. Anyway, I could draw ok Id say when I was younger, but I took a couple of classes my high school had and it really helped. I used to draw and practice every chance I had.
Lately, Ive started drawing again, Im supposed to be working on a drawing for the Virtual Kustomz thread, but haven't had the chance lately(or the patience, damn ADD
But one misconception that people think about drawing though, is that they think they can sit down and draw an outstanding sketch in just 5 minutes. Wrong, it takes a good while to get a good drawing to look right. For a half-assed drawing that looks similar to what its supposed to be, itll take me about 45 min. But for better ones like the one that I posted in the Virtual Kustomz thread, It took me about 2 days to get that one done.
