maybe try to draw things that you normaly dont like little doodles or try traditional art. and your art is great i really like it :D
still love the piece of chariot and moon that you made i hope you get out of this art block

Doodles and doing random lines work for me. Going from a random shape to something completely random I hadn't thought of beforehand.
It's hard to get passed the seld confidence block. Try to remember you're not doing the doodle piece for anyone but yourself. There's noone who's going to judge you , except you. A doodle is allowed to be anything

What helps boost my confidence issues at times is looking back and my most proudest work. Go back to an image that you've truly enjoy making and still enjoy to this day, and reflect on the fine work you've done.

One thing to get you motivated is doing something else for a moment, like watching a favorite movie or series, playing games, etc. The stroke of inspiration sometimes appears during that.

But as I and all of us have said before, you are a talented artist. Your images are amazing!
Blocks are natural, it's just a way of your body saying take a break. And often a break is what was needed.
Hopefully you can relax and fine your motivation once more. Hang in there.
