lineart aside considering all you really did was choose the colors, you're using way too many, your color selection is very weak and uninspired, your hues are too static, look at the art you're ripping and see how they do it.
So tell me, because I've always been dying to know; what motivates a person to rip lines or art? You aren't learning nearly as much, if anything, by not going through the whole process yourself. Furthermore, people who know pixel art can usually tell even without knowing where the original sprite came from, because for example if someone rips lines, the shading quality doesn't measure up and looks out of place. It's a waste of everyone's time.
