|Actually at this angle they're ellipses or ovals. ;) I like the repetition with the paint bottles, but the level of extraneous information in the shot, as well as the fact that the rims of the bowls are interrupted, makes it hard for them to stand out. Also, and this is just my personal preference, I almost never like tilted images. You'll find tastes varying on that pretty wildly. :)
If I were in this room taking a photograph to depict shapes I'd group the bottles together and shoot them from the top, with the repetition in the lids/shapes of the bottles, and then the variety in the colors. But that's me. This is your picture, and you did a fine job taking it if it's the way you like it.
