Unfortunately, yes. Your entry is too late
As it says at the top of this thread -
Welcome to the next Reason To Fly (RTF) Photo and Video Competition - running from 00:01 Sunday, July 18th to 23:45 Saturday, July 31st.
Once the poll is posted there is no way to add entries to it, besides which it would be unfair to the other competitors.
However, a fresh new challenge has just started. This time there are TWO subjects - NATURE or SYMMETRY and you are welcome to submit images for either or both. That competition closes at 23:45 on Saturday, August 14th - set an alarm on your phone!
