Not funny. [Edit:] I realized my comment was no help to you. I'm going to elaborate a bit, I don't want to be one of those who ain't got anything constructive to say ;)
The reflections in the orange head are distracting. The painted seven doesn't look good, it gives the impression of you not being very interested in this challenge, which I'm sure isn't true. The depth of field is good, but there's still too much going on in the background. And this doesn't fit the challenge very well. Just painting a 7 in there is the only link to the challenge I can see (though I might be missing sth).
I bet you're having issues with people finding all seven here. But...very interesting perspective on the watering can, and nice focus. I'm not sure what the black thing is in the upper left, replacing it by moving the small pot up there might help by allowing for a more continuous curve/frame of pots, eliminating that distraction, and making the "seven subjects" less of a treasure hunt.
i like this shot, but feel it doesn't really hit the challenge. the only 7 i see is written on the spout, and the description called for 7 objects, not the numeral 7. i really like the reflection in the spout. hope it does well.
