I'm afraid its probably due to my poor all in one printer/scanner that you can get any detail out of the edges however in the print they are a deep black with detail
How about posting a straight print? as it is, I get the deep black with detail but I am asking myself why it is there to begin with. There is also what looks like a burn/dodge halo around part of the tree. Basically I think there was too much done to an already nicely executed image.
Very nice print. The composition found is so delicate, sad, with frisson effect. But I feel also that the dodge-burn is too hard. Among the lighter strip along the tree (as mark mentioned) the vignetting has strong jump along the horizon. r.
