The two things I noticed about your sprite right away are the cape/thing that goes slightly over his face, and the hair. The cape stands out because the palette is so different from GR's and it doesn't fit too well, it's too desaturated. The hair well.. is looks kinda like a big mess =/ Three little suggestions I could give you would be to not try to fit as much detail in, once again use GR's palettes or make sure the one's you're making have similar saturation and contrast, and to give it more volume. Right now it looks like it's a bit stuck to the head.
Here's a little 5 minute doodle I did. It's not so awesome because I didn't bother going back through and refining everything(like I said, 5 minute doodle) but it should still help you in the right direction

I was waiting for you to do the hero with the scarf, he's my favorite ^_^ His little cowlick is a bit distracting though, if I were to use the sprite I'd probably erase it or at least make it smaller.
Exactly what kind of hairstyle does the lancer have though? O.o I could never figure out what it was supposed to be xD
