I realize you know criteria and are trying to start a conversation here =)
A weather vane is often a mass produced object and we have been told to use that first reason to reject in that situation:
If your description has errors, I don’t see them. Could it be something about the location or a disconnect from the title? I don’t have enough information to have an opinion on that.
If this weather vane is by a artist, or has special significance in some other way, I don’t see it in your presentation.
