Hi Tim,
having been messing with LR3 and PSE for a while, I still find myself shuffling furtively back to Silkypix simply because it is just such a good interface. Making subtle changes to perspective, for example, is just so easy to do! Not that getting it right is easy, but a nudge here and a nudge there on vertical, horizontal and rotation and also correcting for barrel distortion and the like; the possibilities are so easy to explore.
Think you have pretty much cracked it on this image iws!
