I'm sure you know by now that the primary reason this didn't do well is that the viewer has no way of telling that this is in a garden. You have to show it. In addition, while the droplet crown is very nice, to do well it will also have to be sharp. If you look at the other shots like this on this site, you will see the ones that do well are very sharply focused.
I see that this was your first challenge. Don't be discouraged by your low score on this one. In time you will see what it takes to score well, and your photography will improve by being here.
Perhaps you have a birdbath in your garden and this meets the challenge. However I think you have gotten too close with your composition and forgot to include content showing this is related to the garden.
Nice capture of the dropplet and I like the colour. Not sure how this relates to the challenge though. Perhaps your title could have given us a better clue.
