A desert swirl

[GB1]

Shot this out in the Anza-Borrego desert at Thanksgiving, but just had it developed. It had a serious greenish cast due to reciprocity failure.. I spent about 10 min taking it out, mostly. I should kick myself for forgetting to attach the color-adjustment filter I bought just for these night shots.

I have shot these before but have been disappointed with the lack of an interesting foreground. This time, I shot a friend's tent and had him fire an unattached flash twice at 50% power. After that he hit the hay and the exposure went for another 4+ hrs.

Comments? I'm interested in hearing whether you think this solves the foreground issue (??) Also, as far as I know these type shots cant yet be done with digital cameras.. the battery would go dead and, possibly, there'd be too much noise.
