Update: check bottom post.
Making a small illustration for an orchestral performance thingy (Berlioz's Symphonie Fantastique). As such I'm thinking more of a representative look as opposed to high-detailed scene, seeing as it's a musical performance. At the moment I'd say I'm at the barest of stages in underpainting - basically, the symphony's a drug-addled journey following one dude's unrequited love for a woman, and it gets really weird toward the end (a Black Mass...). Any starter tips, etc, throw them my way.
Back in a few hours.
