With some artists, no matter what medium they use, or how they use it, you can tell it's their art. The content or the method doesn't matter, you can tell it's theirs. That's what I would consider a style. It doesn't seem to be something that can be controlled, or found. You seem to be talking about a preferred medium and method. If that is the case, why would I want to stick to one?
1. Yep! I love it, love it, love it! 2. It took me 18 years to find it. I had some sort of artistic epiphany and my drawing "Give Up Your Ghost" was born that day. I've stuck with that style for most of my drawings ever since. 3. 99% of the time it's made up. There was a girl who used to go to my high school, and she graduated 3 years before I did. I never saw her in person in my life but I knew her brother kinda well and I was sad for him to find out that she had passed away in a car accident the year we graduated. A few months after she died I came across some of her artwork and it was so incredible and so similar to mine. She inspired a couple of my drawings and after I finished them I left them at her grave and thanked her for the inspiration. 4. Probably the shading and the shapes. I don't use any color. I also like the surreal and strange kinda thing I have going on.
1. I love my style now, but I doubt it will stay that way. I don't mean it will permanently change to a completely different way of drawing, but things will definitely evolve within time.
2. About a year ago. I tried to draw anime, but it nothing quite clicked for me. I moved on from that and tried several cartooning styles instead, and eventually developed the one I do now. It's still a work-in-progress, but I am definitely better than I was in the past.
3. I actually combined several styles together from several aritst; what I did was list what I liked from each, and put them all together to create my style.
4. That's a tough one, but I think I'm most proud of my anatomy with my characters. I sucked HORRIBLY when I first started out. I'm still a bit rusty when it comes to proportions, but it is a definite improvement than in the past.
