I can understand a part of the controversy - it may not fit within the "Conditions of Entry" definitions:
"2) ENTRY ELIGIBILITY: Entry must be:
· A new portrait completed since 1 April 2015, owned and created by the artist; not
previously exhibited (including online but excluding the entrant’s personal webpage or
social media platform), shown in competitions or awarded a prize;
· Photographic, archivally sound, still and two-dimensional;
· Within the size limits and able to be hung on or pinned to Gallery walls.
The Judge will be looking for excellence in photographic technique, creativity and originality
to the standards prescribed by the Director, Tweed Regional Gallery."
But IMHO, it is sufficiently interesting to be worthy of display.
