there's A LOT of improvement can be done, but we all learn bit-by-bit right? lets talk about two basic things u can slightly improve here

1. i can imagine u standing up straight and taking the photo. a good way (especially for cityscape shots like these) is to crouch, or go as low as possible, then shoot. you would want to show a scene/perspective that would be new for even a person who goes day every day!

2. spend some time learning basic photo editing software, if u havent already. some photos here should've been upright but they're not. this can be easily corrected in any photo editor.
