First of, I really like the idea of a super homophobe girl figuring out that she's gay. Other than that I have pretty much the same problems with the comic that Nez and Chanteluni already told you.
I'M CURRENTLY WORKING ON A YURI COMIC ENTITLED "GAME OVER"
Titled or named, not entitled.
What do you use for drawing? Doesn't look like your using a drawing pad, I'm guessing you work with vectors? Anyways, I think the art does look a little bland, on a detail level. Some highlights and a few more shadows should help make the drawings less plain.
