I just came across this thread and I've gotta say your style looks like you've been working in the field for years. How far along are you in college? Like, when you say 'too late to change majors' does that mean you're a senior? I mean, you can change majors pretty late in the game, and no thave to backtrack too much.
Anyway, I'm sure you've heard it all before.
Your images are phemomenal. The fifth one down in your first post is my, IMO, the best one in the thread. I love using a ball point pen. It helps giev you an idea of what lines really matter, and which one's you can leave out.
Just wanted to say I love your work, and I look forward to seeing more.
