i highly reccomend ibis paint.
and Im pretty sure that my style is way different then yours, other then the really harsh shading you do on yours, I dont do shading. [mostly because I suck at it and prefer a simplified version] Just try it, I didnt like ibis paint too because it seemed really pretentious and it lagged alot [mostly because of my storage] but it was pretty nice, and now its awesome.
[Also, showing my art to prove if its highly reccomended isnt really helpful. Im not a complexed artist or a professional good one. Im more of the simplified cutesy art. Half of the time I just draw cats.]
Im sorry but Im not gonna try and sugarcoat this, if it sounds harsh Im sorry. It does look bad, especially since theres alot of shadings and light from it. but Im not saying this to make you quit art, its to just say that theres still alot to go, and kinda insulting someones other art for looking at what it is? its kinda sad.
It seems you're a beginner, you should try practicing your actual drawing skills instead of just making gacha edits, cause once you learn how to draw the gacha edits are also gonna look better, tough of course it's not easy peazy to actually get better at drawing but we all start from somewhere, I myself used to spend so much time and effort on the drawings and yet they would still turn out looking terrible, so i have my own issues with my drawing skills that I wish I could fix and I just can't but I think we'll all make it someday.
Tried to give some advice, please don't take any critique to your stuff as "attacking" you
