The last one is a beautiful sunset shot, love the twigs.
The second one is a so, close, yet so far shot. The rising and falling line the cat tails create makes a really interesting composition. However, it get's derailed on the left side of the pciture with the incldsion of the shore. If you're ever going to try a similar shot, try your best just to get the faraway shore, lake, and sky, then the line and composition won't be disrupted.
I like the first one, it's very pretty, but there tends to be little interest to it.
The third one... doesn't work all that well. The red, artificical lines of the ATV take up too much of the picture, hence all sense of movement is lost.
