Don't wish to discourage you but none of these photographs have any sort of appeal to me. Poor subjects and improper lighting can be used to sum up all these photos.
#1 - Focus is off and there is camera shake. Such photos need to be deleted.
#2, #3 - Bokeh lights are nice but I would suggest you try to have something in focus as well.
#4, #5 - Uninteresting subject. Try shooting flowers rather than plain leaves or at least choose an interesting leaf. Shooting flowers is a good idea since you can experiment with different compositions
#6 - My eyes searched for a few seconds to see what you were trying to show in the photo and after 5 seconds I finally located the barely noticeable pigeon. A good photo should (at least when you are still learning and wish to stick with the basics) have a clear subject (like a cat, flower, person etc). This photo has nothing to hold a persons interest.
#7, #8 - I see you are trying some selective focusing which is good but your composition can be much better and the fluorescent lighting isn't very nice. Try shooting the same subject with different angles and preferably with natural lighting.
#9 - 11 - I am liking that you are trying experimenting with light and shadows but again the lighting is poor and the subject is nothing special.
I suggest you choose better subjects and read up on lighting. Fluorescent tube-lit photos rarely (if ever) make good photographs and I haven't seen even one subject in your photos that was worth photographing.
Please don't be disheartened. I am an arm chair critic, nothing else and all you need to do to improve is to keep shooting.
