I can't work out where this advice doesn't connect for you..
maybe go back and look at that kirby sprite, he's a pink blob, and he looks a lot better than your sprite
edit-
actually, it may be because..:
just about every game in GM uses stick figure, or blob sprites, and I've long since gotten sick of them, hell, even though kirby has some fantastic sprites, I'm sick of him.
with your blob sprite, we don't have much to work with, its a pretty bland design, boring colours, simple animation.
and every edit we have offered (save for krut's fantastic edit) hasn't been noticeably different
