Images that tell a story are always much more appealing than passive ones. This is an excellent response to the challenge. Your thoughtful title puts it in context and involves the viewer. The colours are subtle and attractive with the flattish light conveying the grey overcast day.
To score really high, you will need to be mindfull of composition and the rule of thirds. The column is such a dominating feature in the photo that to have it centred loses the potential of its power. I would encourage you to re-crop this for your own interest and report back after voting on how it looks with the patio heater just touching right of frame which would put the pillar on the vertical thirds line. Without putting a grid on it, the impression is that it's not straight although that could just be the heater or sloping ground under the table?
when i read "rained out", i think "black and white image"...
it's such a pretty setting, but empty--the pulled-back image lacks energy, imo.
i would be interested in seeing how this image would look as a closer shot, or as it is currently set up but with someone reacting to the wet environment...that kind of thing.
