Indeed - the main reason I have posted a few scans of my prints is for that very reason: so people can see what I do. If they elicit any considered comments on how I could perhaps improve them, that is a bonus (and on at least one occasion such suggestions have added to my arsenal of tricks).
However, as already mentioned by others, there are a multitude of reasons why people do not post images. No conclusions should be drawn from the fact.
P.S. - I thought Members could not see the full Gallery?
