Thank your Gandma for opening your eyes!  :)   Now I see some visible differences at first glance.  You're on the right track now, but you aren't going to like this part.... she still looks way too similar (IMHO)  to V4 (could pass as closely related IE: sibbling) to be considered a "unique" character and at this stage in the morphs, I'm not sure that Daz would accept her because of the similarity.

I'd like to suggest that you change the shape and position of the eyes.  Currently they appear to only be moved out so that they are more flush with the face instead of inset like default V4, and you applied a bit of a slope to the outer corners, but other than that they look way too default in appearance.

You're on the right track now towards creating a unique character (you acknowledged that the previous attempts needed altering).

Once you get the facial features and body morphs honed, then we can all get more into your textures ;)  and some can even teach you about shaders which will help boost your character and give her some selling points :)
