If there's a hummer around, it'll see your feeder where it is. I'd guess that there're hummers in the forrested area near your house, but they have enough natives to keep them happy. From a survival standpoint, it wouldn't be smart to expose themselves during a flight across an open area. JMO.

Another thing you might do is to put some red bows on that tree to draw them in. Your neighbors will wonder why you're decorating the wrong Christmas tree;). It might take weeks for them to find it, just make sure the food is always fresh if the feeder is out there because if they visit when it's gone bad they might not come back.

I certainly would not suggest painting that lovely table, but a little more red would help. The country setting looks great for hummers. If you plan to sit at the table to view the birds, you will need several birds. You would have to be fairly still long enough for the bird to approach, sit on and then feed from the feeder. Just a little movement from that close will run them off; if I move my hand or scratch my nose, my birds will move to another feeder and I am 10-12 feet from the nearest. A cough or sneeze from 30 feet will do the same. The feeder looks a little hidden by the tree. I would go the extra yardage an put up another feeder.
