I was all set to give lots of supportive and constructive comments, but I am not sure you actually seem to want them, you seem to just want instant validation or else you will give up - I have no idea, but you come across as rather young if you have that understanding of how to learn...
if you have something in you that loves photos you see and would like to create them, then that is all you need, but don't quit immediately...
the photos are okay for beginner - they show evidence that you are thinking about what you are taking - the buildings show that you pick up colour as a reason for the photo etc. but no, of themselves they are not good per se.
However, if you were interested in learning it wouldn't take much more than 2-4 hours with a good teacher to transform your photos, in that time you could cover the basics of:
- composition
- lighting
- the exposure triangle (i.e. how cameras work!)
and at the end you would be taking very different quality of photos
but you would need to be prepared to listen to constructive criticism and want to improve, and I am not sure that seems to be the case...
(for reference I am a professional photographer and have taught photography to beginners / improvers internationally).
