At 1x, this sprite is barely readable; it somewhat hurts my eyes to even try to focus on it to see detail. At 2x, it's a little better but it's far too thin for a sprite of it's height. I would suggest creating a bigger sprite. Perhaps more like 24, 32 or wider in pixels. If you want to create small scale sprites that still have good readability, I would suggest studying the characters made in older RPG games that were not much taller than yours.
