Aesthetically, you can throw Kolin into the stereotypical SF2 cast and she would fit.
That makes her better than the majority of the 3s characters.
No defense over Ed though.
She doesn't fit in SF2 and that's good, because a lot of SF2's characters are boring visually.
She looks like an SFV character aesthetically , if that makes sense.
Instead of trying to lump her into some cast of a past time, embrace the new aesthetic. Trying to get characters to look like they came out of a previous game ends up bad. Like the pile of uninteresting shit that is Abel
