I think Louise is a very decent dancer, but she is just too cautious in her expressing sometimes. She knows it anyway, as she's already alluded to it outloud, but of course saying you're going to try and do something and then actually doing it aren't always easy if you're that tentative in your approach. I've seen Louise go full throttle esq in dancing (from her pop career) so she can def apply oomph/energy etc (be it measured) if she really wanted to. I get she's aware that her kids are watching and she doesn't want to embarrass them or her husband, but she's not doing that anyway, and so she can loosen the fear a bit more. Maybe she needs a pep talk from someone that has a tendency to always get 'it' out of her.
I think she's still better than plenty in there so would, just for her talent, pref she stay over some others, but I think she needs to step even further forward. Her dancing is decent, nice, even pleasant, but she needs to add the sparkle (as cheese as that sounds). She has it in her, she can diversify, but the limitations are all in the head for her, which is a shame if she doesn't get past that.
