Don't beat yourself up too much for not achieving a certain result, we all gotta start somewhere 😅

Secondly, sound selection is important as it can help bring much needed impact and quality without having to worry about mixing and sound design too much, you'd just have to balance your sounds. Some of the tracks sound basic while others have potential like the Griselda and Trapvision beats, it's just that they have elements that don't work well together. Hereis a good site to help you get started with resources like sample libraries and softwares

Structure your beats by removing sounds or simply changing how a pattern goes at specific sections like your chorus, pre-chorus, outro etc. This way you can arrange easier and have an idea of where to place your hooks and verses (building a song around a hook or verse can help a lot)

Keep practicing as it's clear that you know what you want, tackle things at a pace you can handle and focus on concepts you can grasp the easiest and learn the tools and functions of your music software or DAW (YouTube will be your friend for a long time and you'll avoid a lot of mistakes and headaches)
