I agree,in my experience,photographs never really portray what I really want to convey. Sometimes I think this problem may be simply a case of trying to photograph at the same eye level as the artist was when making the work...or perhaps if the work was photographed in the round (as in a video) that might help. As I work, I keep spinning the figure to get a sense of the complete figure..with all the flowing shapes and rhythms. I must say also that photographers who use lighting and photo-shop can often enhance work to an extraordinary level. Lately I have insisted on more natural images so my clients know what to expect.
I was interested in the response you received from the public...so I'm glad it was favourable.
Please don't be intimidated by 'more experience'. My advice to you is just be sincere, work out what you really want to say, forget current fashion trends and be true to yourself. As artists get older they are often aware that their time is running out so they avoid wasting their energy on 'unimportant' works.
