Well I see a lot of edits, but not much in the way of demonstrating original works.
I mean, it's somewhat competent but there's a lot of sloppiness going on where you haven't simply recoloured existing parts of the sprites.
Starting from the top:
This in particular looks ridiculous, because you've pasted Cynthia's hair over Candice's face without taking into consideration the differences between their sprites. Namely, Cynthia's head is larger, and drawn at a different angle to Candice. So, what we're left with is someone with massive hair that engulfs their head and lies at the wrong angle compared to how their head is supposed to be facing.
These are slightly better composited, but then they're made up of about three or four different sprites stuck together like Frankenstein's Monster. You can never make something that looks like a real piece of art this way because it's not - it's just a mish-mash of things from different pictures that were not designed as a cohesive piece.
Meanwhile, the parts that you have made minor edits too suffer from poor-quality outlines that are mostly solid black lines, and generally a lack of ability to fill in the blanks where copying and pasting can't.
Same again, sprites haphazardly smashed together and quickly recoloured, without enough skill to be able to complete the parts that you couldn't copy from another sprites.
I know actually drawing from scratch is hard, but simply cutting bits and pieces of other sprites together only covers the very basics, and won't teach you much about creating art for real. The rest of the way to being able to showcase your art is to practice drawing without using the existing sprites as a crutch, and learning about artistic principles - although first you still have a lot to improve on drawing lines and colouring things in to match the official style.
I personally don't think you'd be able to satisfy anyone's request just by giving them sprites made by cutting and chopping existing ones with crude attempts to sew them together - especially when you come to something that can't be mostly copied from other sprites.
