Why does it feel like my skills are declining as i try to improve?

I've been on a quest to improve my writing. I've learned a lot so far, including great writing habits. But I've started to feel like my skills have been declining.

When i started out, i was a great at description. I was just worried about my vocabulary and the technical aspects of my writing. I wrote a lot of things i was happy with and, while i didn't write a lot, when i did write i was able to sit down and write out really long pieces.

Now, I've started writing down ideas and daydreams as they come to my head. While it's great for getting things out on the page, I'm worried that my imagination is suffering because of it. I've also started trying to improve my technical writing skills like, sentences, sentence structure, grammar, and some vocab. But I've recently begun noticing that my tone and description skills are declining as well.

I've noticed i'm not daydreaming as often as i used to. When i try to write out my daydreams, i fall over myself trying to find the right ways to describe things. Lastly, my tone feels insanely robotic and dull.

I think I've been at this for a few weeks. Maybe a month, or close to it.
