I have to agree that no matter what resources you make use of to pick up new ideas and techniques, actually trying those techniques is the only way to progress. On the project I'm working on now, I've done something I've never tried before; pre-shading panel lines. A lot of folks won't consider that to be an advanced technique, but for me it's something new. Did it come out perfect? Nope. It did, however, come out well enough that I've learned something from the experience and will keep at it. Next time, I might try engine wiring or using BMF; who knows?  Whatever it is, it's gonna be awesome! ;D
