The first one looks very very soft, and not very interesting in the first place.
I quite like the other two, though. They're pretty good pictures of sculptures in context. Nice work getting down low, these are two sculptures that, to my eye, benefit from the low angle.
I think they would both benefit from a slightly wider angle of view, to give us more context. You have the beginning of an idea in the second one, showing us the echoed shape of the sculpture against the building behind, there are some repeated/parallel lines in there that's nice.
The last one gives the appearance of tipping toward the right. I'm not sure if that's an optical illusion, or if you actually tilted the camera a bit. Either way, I think the photo would be better tipped the other way a bit to make it appear more "upright"
