First Impression - the most important one: The pattern really works, the colours work, and the border complements the picture well.
Composition: The angle that you have chosen for the lampshade works well to give the pattern required for the challenge. To some degree I wish to see more of the edge of the shade ... but am not sure if that would work.
Subject: The choice of a lampshade is inspired. I did not actually figure out during scoring that this is what the photo was of.
Technical (Colour and light): The colours are nicely contrasting. Using a border for this picture has worked well, and unlike some other pictures that I have seen it has not counted against you having one. The lighting and DOF are both very complementary for this shot..
To grow its vote?: It is a good shot, this is a solid portfolio shot. There are many subjects and treatments that are fine photographs but just don't get a huge popular vote, this is just how things are.
Summary: The picture is really good, and it works.
