That's unkind. The OP asked for opinions, not sneery nasty jibes.
OP, I'm pretty sure with practice, you can improve. Your photos have a certain vintage feel to them, and are quite unique in that respect.
With feedback and practice, you can hone your skills and style to work on composition, aperture, exposure, ISO settings etc. Good photographers use the key basic skills and then "bend" the rules at times to get the best photographs from certain scenarios, subjects and the effects they want to achieve.
Do you have any books or magazines on photography? Maybe going back to the basics of the photography skills and image composition will help you. I used an old manual Canon SLR which was a semi automatic and I used it on aperture priority mode as it waa easier to get used to it.
I find studying good photographers and their work helps too, as well as learning digital media skills to help with the processing after in apps like Adobe Photoshop etc
