Good sprite, but possibly too much texture.
And I agree with onek: if you have a lot more, make sheets... ;-)
He was actually called Jitan in the Japanese version, so it's not much of a stretch.
His name is Yitán in the Spanish version? Interesting. Wonder why they changed it.
u should make all the sprites transparent and maybe upload them alltogether in one file
this has potential, but theres also a lot to improve, some parts look rly jaggy and need aa, right hand looks a bit small, a bit pillowish here and there, and most important... work on ur colors right now u have about 42 of them, thats way over the top, in pixelart u should try to reduce ur colors to a minimum, the are several tricks to do so, using grey as a neutral,universal color which can be used as a connector in ramps for multiple colors, for example... maybe take a look at THIS...
made a quick EDIT.... reduced to 10 colors, see how it looks even more colorful?... i also did some aa, and correction on the face
