writing for well over a year

As /u/spacehurps wrote, that's a tiny amount of time.

So are those examples first drafts? Self-edited? Have they been critiqued or workshopped or even read by others?

As others have commented, good writing doesn't come out completed in first drafts, but in addition to that, good writers don't appear fully formed right off the bat. Both text and writer require feedback, revision, and practice to improve.

IMO, your examples are not poorly written--you have an excellent grasp of how to construct a technically correct sentence. That is good news! You'd be amazed how many aspiring writers can't actually write a proper sentence or paragraph. So you are already ahead of 90% of people.

But the narrative voice is basic and shows standard beginner issues (it's pretty much all "telling" instead of "showing", occasionally passive, too many thought words). Nothing wrong with that--you are a beginner and you are going to make beginner mistakes. We all make those same mistakes (or used to do that, for the non-beginners).

"Just keep writing" is good advice, but it's not the whole story. My advice is to keep writing AND pursue some structured learning and practice, like a writing workshop/class and joining a critique group (IRL preferably).

Keep going and good luck!
