Had time to rewatch her performance objectively and go beyond who she sounds like. I think it's a little unfair to compare her to Jennie OR Rose--they're artists who have gone a longer way in terms of training than Andrea. THAT BEING SAID, what she has in SPADES is voice control. Notice that every time she ends a sentence, it's natural--neither rushed or too elongated. Not to mention keeping the pitch and going in and out of vocal and rap. This is particularly difficult given that she's dancing at the same time, and having stage nerves in general. It wasn't that she isn't nervous--rather, she is just really good at keeping her composure and maintaining the quality of her voice all throughout. I think that is her biggest vocal strength, and something she can take and refine if she does pursue a career in KPop.
