I am a fledgeling myself, so here's some general advice

Format your text, there are guidelines pined at /lit/. No matter how good your writing is, noone will read it if it looks like a solid block of text.

To write better, read. Preferably in a genre you want to write in.

Don't limit yourself with visual descriptions. Use all five sences, (vision, taste, smell, touch and sound) and more (emotions, urges, regrets etc).

But if there's anything you NEED to learn - your writing will suck, and that's okay. It will take a while before you get good, but you will never get good if you never practice.
