I like the composition. At first I thought I would have liked to see the whole plant, but the pots are really the subject so that's ok. I also like how the right side of the wall starts square in the right bottom corner. One minor thing that nags at me is I would like to see the bottom of the first pot. I'm also thinking the first pot sould be equidistant from the top and bottom of the image, but that may sacrifice the edge of the wall in the corner. Perhaps you can drag the right bottom corner out diagonally to keep the wall in the corner and show the bottom of the pot?
