I like it but prefer it as a boys name.
For some reason I don't like any girl names that begin with D, just my opinion.
Also I think there are too many young boy Dylans around for it to be used by a girl, maybe in a few years when those boy Dylans grow up, there can be a new generation of girl Dylans as I suspect it will eventually become more of a girls name. Similarities with lyla, Lila, lily. Also Riley is becoming more of a girls name and it is very similar.
