I'm a noob so please take what I say with a grain of salt.
IMO they all look like snapshots.
#1 - its just a picture of an older truck. The composition isn't good and the sky is blown out (white).
#2 + 3 - such vibrant colors!!! Do you know what your settings were? The colors came out gorgeous! Once again though these are snapshots. It's like you just took them on the spur of the moment with no thought of composition.
#2 - what is the focus? The sky, the grass? There are people, cars, benches, buildings, etc. to the right of the frame. The sky is cool looking.
#3 - Love all the bright colors! But once again lack of focus and composition. There are people hanging out in the right of the frame as well as a telephone pole and some other stuff. I did a quick edit of this picture (basically just a crop).

MT Vision Photography,
I just wanted to give you an idea of what I meant about composition. Everything else in this picture was basically clutter. Get rid of all that junk and its actually a decent photo. When you are about to snap a picture...stop...and look at what is really in your viewfinder. If you are taking a picture of a landscape then you don't want people and cars in it.
Like I said before, I'm a noob and this is all my inexperienced opinions!
