tl;dr pls halp tell me what I'm doing wrong with my pictures taken on iShit 6 Plus

Alright so for some reason I suddenly got interested in photography, but as I am a "poorfag" and can't afford a DSLR, I have to use my iPhone 6 Plus to take photos with, which by the way has a shit sensor with pathetic aperture and crap zoom. It's also mounted on some $10 tripod I found in my parent's attic
I've watched a bunch of videos regarding composition and I also bought the ProCam app for my iShit which allows me to manually adjust shutter speed, ISO, whitebalance and focus, and also features cool stuff like long exposures. It also got an image editor that can apply post processing effects like adjustment of highlights, contrast, saturation etc.

So here I will post some of the pics I took this weekend while at my cabin. I feel like there's something wrong with them. Of course, don't expect amazing quality of the photos with no grain, especially considering it's a moron who took them

Now I expect I am going to be made fun of here for using a shitty phone camera to shoot pictures. I honestly don't give a shit if you call my photographs garbage or crap. As long as you can tell me what I am doing wrong I will be happy so I can become slightly better than a retard
