I really wouldn't lose sleep over that, or whether you have your own "style." Just focus on creating good art!
I think your shading and colors in general are a great start. The forms are a bit blobby/pillowy, and the dithering just makes things more indistinct. Especially if you are inspired by megaman ZX sprites, you want first and foremost to have good clean forms that read right away, even at this small size. His face looks a little funny to me, like he has a pinocchio nose that is too far down. The kick animation is very hard to crit since he has no upper body and there is no actual animation to view. The handle of the sword looks nice but the blade looks very erratic/nonsensical, almost like a very, very exaggerated katana edge. Think about how light might actually strike a flat sword blade; probably you will not see a black and white sine wave! There are loads of games with pixelated swords out there, all the recent Castlevanias come to mind as a place where you could look for inspiration.
Good luck, and welcome to pixelation!
