i'm a sad individual so here are my not good sprites

Your technique is highly flawed however because of many reasons.

While indexpaint is a very valid way to make pixelart, you are doing it in a way that goes against the very fundamentals of pixelart:

Sharpness and readability over anything else.

As a rule of thumb, you shuld always use this technique for big pixelart. Like, 200 pixel and onwards, never for game-size pixelart. This resolution will cramp all the drawing you did and ruin all the detail that you've put into the drawing (this is a recurrent problem in your art, which looks unreadable and filled with stray pixels).

indexpaint, then, should be used in a smart way, and not in literally all instances of pixelart. There are times where placing the pixels on your own will yield much better results.

This being said, you should always make indexpaint in a very large size. For example, for a 200 pixel tall sprite, you should draw it in a 4-times bigger (800 pixel tall) canvas space, and then resize it down to 200. This will ensure that the pixels will still look sharp despite being done with digital art. Remember that since you're making a drawing 4 times bigger than the final output, try using a 4 pixel thick brush to draw the outline

Avoid blurry brushes and brushes with pressure sensitivity, too, as they are the main source of pixel noise when color reducing. Try using a 100% hardness brush, with the blurs used only on spaces where shading should blend more. This will speed up the process and yield readable pixelart.

In other words, if your sprite is smaller than 100x100 pixels, then do it by hand. over that size, use indexpaint wth aforementioned techniques.
