There is a difference between "inspired by" and "edited." Here is a mask of places where your pixel work matches the original sprite exactly (or has been shifted by a single pixel in some instances):
The bulk of the feet were simply copied, but there are clearly areas where the face, leg, and shoulder were not fully edited away from the original either. Also, the following palette similarities:
1 outline color
4 hair colors
3 base clothing colors
3 skin colors
Your palette differs only in that the original has a block of 4 armor colors, whereas you share that block between armor highlight and belt colors. From what I have seen around here, sprites "inspired" by other games rarely share exact blocks of pixels or identical palette layouts.
The only reason I am going to all the trouble to point this stuff out is your edit of the sprite has changed it for the worse. Without understanding the basics of color theory, painting and pixel art, sprite editing will not be able to teach you anything. Study, practice, and make your own sprites; it is the only way you are going to be able to improve!
