Thanks for the advice, guys, some of it I took and some I didn't. :P I tried doing the engine glow entirely in Bryce with some success, but it just wasn't good enough, so I added a touch in Painter. The only other postwork is that the stormie in the lower right went way too dark on the last render, for some reason, so I lightened him up in Photoshop. I'd value any other comments or criticism for future reference...I probably won't apply it to this particular picture, though, since it took up every ounce of RAM my poor ol' 603e had and took 14 hours to render....
