I was talking with an artist friend the other day, and he mentioned to me that he like to experiment a lot when he's drawing--to just sort of start drawing with no precise idea of what's going to happen.
I told him, yeah, I do that too. And it reminds me of something I've heard a number of times from artists who are starting out.
This one I found is typical:
When an artist views their work, they are comparing it to what they had in their head. In their head every line is perfect, every bit of color is spot on, every bit of anatomy is correct, and every little detail shines through. To compare what they see in their head to what they have on paper can be devastating. Your hands have to learn to depict what your mind sees, and unfortunately, that is a very long process.
I can imagine that would be frustrating. It's not how I create, though, and apparently not how my friend creates.
I think there are as many different ways to be an artist as there are ways to be a human being. There's no such thing as "doing it wrong." All advice, as they say, is autobiographical, and with that in mind, here is mine:
Don't try too hard. Don't hold what you create to a rigid standard of perfection and then get angry with it for failing to meet that standard. Make it as good as you can make it, and let it be itself, and over time it'll get better and better.
YMMV.
