How can I get better at writing? I dunno.. I don't really like my writing to be honest xD I don't feel that I'm descriptive enough, are there any tips on getting better at writing stories and stuff?

Add more adjectives to make your story more detailed

Try to be more descriptive. It sounds hard to do, but it's not if you keep writing. Add in more details. For example, instead of "The sun glowed across the valley" you could say "The sun's brilliant beams radiated the green expansion of land below."

Just write more. I know It sounds like it doesn't sound helpful, but if you want to get better at something you need to keep doing it. Reading more books will help also.
