She was obviously different looking, but not enough to affect the portrayal. She did an great job, which is generally true of all the Borg Queen actors.
She's not my favorite actress in the role٫ but she still did an amazing job. Her presence in any given episode certainly doesn't diminish the crush I have on the character (which I'm sure everyone is sick of hearing about by now considering how often I bring it up. Sorry٫ I just can't help it!)
