I personally like both styles. And I may be wrong about this, but I feel that your work often has less hard outlines and highlights and relies more on contrast between large clusters and bigger fields of colour. I sort of feel like that's your style, and it works very well in this piece, as in others.
This piece is a good example.
http://www.pixeljoint.com/pixelart/92604.htmI feel like there's so many places most pixel artists would add more dark outlines and/or bright highlights. I'm fairly sure I would have known this was yours without looking at who uploaded it.
So keep developing your style, I say. It works well here, as it does in your other pixel art.
