I love a good portion of these OP, my advice is to sloooowww down. Some of these are blurry because your shutter speed was slow and your hands were too fast, some of these are that off black color because your shutter speed was too fast for a proper exposure and you had to take the shot handheld. My advice is to take a deep breath in and exhale slowly as you steady yourself, balance the composition and take the shot. Pay attention to the framelines and how you frame the shot you wanna take. Take into account the lines of your composition and make sure everything is nice and straight or at the desired angle. The focusing seems to be off consistently, but I suppose slowing down and pay attention would fix that too.
Have a photo of mine in exchange for listening to my monologue. It's nothing special but I like it, maybe you will too.
