Good question Graham, I note to date 117 have read your post, I'm the 8th to reply .. yes it relates to posting on the Gallery .. yet it would be greatly appreciated if more would post and get involved, the more the merrier ... and that is a case in any thread ... you've made some fair comments in a few threads, more so than some pros' or lack of them.
Any Forum it is difficult to judge the work, less we know a person or one states they're new, I've seen a post on another Forum before of the persons first ever post, given it flagged newbie as well .. the piece, as you guess created feedback as to an excellently produced piece in every form .. That newbie was Mr Smiley himself ... Les Thorne ..
.. goes to show you may not know by a pseudonym the degree of a turners experience.
It's down to does a piece tick all the boxes, stand on it's merits, well executed, you can reflect on past posts or if in a Club, should it hold a Competition, the standards of work/detail/finish normally give a better impact with the size and being in the flesh to speak, gives an idea as to what to look for in critique, it's with anything the more anybody gets involved the more they've a better understanding.
Cheers David
