this is cute, I like the little dolls, and the font is cute. is there any way to maybe go with Braids for the hair. Also maybe shorter dresses longer legs and black and white checkered boots?? Is there any way to incorporate stitching and needle and thread? Also maybe different girly colors?
you really should upload some photos of your dolls.... my take is that if you make it look exactly like your dolls then you have limited your ability to expand.
But if you do want your exact dolls why don't you do a fun wordmark and add photos of the actual dolls???? to the logo????
