The last image, I think, is the strongest one. Are those streaks in the lower left reflections in a pane of glass? If so, you might try a polarizer in that type of situation if your camera will accept them. Polarizers can frequently all but eliminate reflections altogether.
Photography is skill and art mixed together and impelled by vision. It is important that you learn to be able to record what your mind sees. So you have to be able to understand what elements of the scene in front of you actually need to be captured and then you have to build up the skills to do that.
It is very difficult at the beginning but the important thing is to take lots of pictures, but for each picture, try to understand what you are trying to capture. Eventually your skill will catch up to your artistic vision.
Just don't mistake the occasional lucky accident for total ability; none of us is that good. If my 'keepers' ever get more than 5%, I'll be happy.
Out of your 4, I like this one best. Nice geometric pattern and the capture of the bird in flight. Soothing, appropriate colors. Focus is off, but the idea is wonderful.
