My drawing class has 24 people in it. I went from spot 24 to spot 2 in 3 weeks. I also draw like 2-8 hours a day. I draw so much, I stopped doing any 3D work. =\ If you want something bad enough, you'll work for it.
I think the only questions you need to ask yourself are: 1. Do you like drawing? 2. Can you think about things analytically? 3. Are you willing to work hard at it to get better? This is the same for any skill that you acquire really. You have to want to get better, but just as importantly, you need to be able to work out…
