So I've been drawing since I was a little kid and I have always wanted to improve my skills past sketching and into the realm of actual composition. After scoring a fine paying job I splurged and picked up an Intuos 4 to play with. I've been practicing the physical part of it (getting used to the borders of the tablet as well as the feel and proper use of the pen), but what about the other specs?
What image resolution do most artists work in when painting? What are some good brush setting to use to imitate water colors? Paint? Pencil? Do most people sketch a layer and then paint a layer?
What are the basics for transitioning from drawing in a sketchbook to painting on a computer, as far as the technical aspects are concerned?
Thanks in advance.
