Well gentlemen, thank you all for your responses. Peter, your comments about the cropping opportunites is supported by Mike's and Dark Penguin's offerings. I like the penguin's, but Mike's doesn't grab me at all - which means life is not boring!
Peter's remarks about a larger format resonate with me. I'm about to step up from the D70 to something with more mps mainly because I'm not very often satisfied with the resolution of detail.
This image however, speaks to me more perhaps than I should expect others to hear. The circumstances in which it was made (aftermath of a bushfire), the great familiarity I have with this wilderness stream which virtually flows through our garden, the fact that it was a time of drought and the river had virtually stopped flowing .... all of these mean that the image has an emotional pull on me which probably far outweighs any aesthetic/artistic merit it might have.
Some of your remarks about trees, rocks etc., reveal to me how unobservant I have been. Most of them make the image better, why didn't I see it first?
Again, thank you all. I think this is an image I'm going to work with for a while.
BTW I wish I could call you some thing else besides Dark Penguin, Dark Penguin!
