I understand you wishing to encourage your daughter, but these competitions seem rather pointless if they are mainly inflenced by lobbyists
If your daughter appreciated the feedback perhaps join a photographic website and post up photos for critique. Some very knowledgeable people about and some good honest opinions too which can only serve to help a budding photographer.
Even have competitions, but they are anonymous so as to avoid the garnering of votes and are purely talent based.
Looked at the link and although I didn’t vote, will give some critique if your daughter is interested in others opinions
It is a pleasing photo with the cygnet nicely in focus although slightly overexposed in places and crop is a bit tight at the top. Guessing the whole shot has been cropped a fair bit which doesn’t help to tell the whole story and might have been nice to have more of the adult swan.
