If I could give some constructive critism:
Try shooting at different angles... most of these are straight-on and perfectly symmetrical. I photograph as a hobby, and I've found that some of the best pictures are the one that make you think.... pictures that show something people are not used to.
Another thing to think about is how easily you can manipulate the light and reflections. You'll find that all kinds of stuff is shiny and if you can use reflections to accent curves or lines, that's a good way to get an artsy shot.
To give an example, you took a picture of that bronze horse rider... I would have analyzed it and looked for angles that make people think, like a close-up of the horses reins, angled slightly left, playing with the way it reflects from the sun.
I can post a few pic's I've taken to show you what I mean if you want...
