Art Tips For Programmers?

An anonymous reader writes "Recently I've found myself in a bit of a bind with artwork. My programming contracts have been rather small, barely enough to pay myself let alone an artist. The art needs aren't intensive, mostly icons or sprites depending on the project. Despite owning a few key apps (Photoshop, LightWave, Maya) my art production output is rather poor. Are there any other developers who have learned to be self-sufficient? Are there any resources available to educate me on the finer points of making graphics that look professional?" One resource for the less-artistic among us is the collection of free SVG clip art at freedesktop.org, though it won't give advice for creating new art. What are some others?
