Veena, I think a lot of younger siblings would understand where you are coming from. I'm actually an older sister, but my younger sister has been compared to me a lot, and there's no way it can't bother her. Actually, it bothers me sometimes; I really wish people would just accept that she's her own person--I don't see why I have to enter into the equation at all. We are two separate human beings. And it really bothers me when the way she looks is compared to the way I look; there are a few guys who have said some pretty hurtful things to her and it seriously pisses me off. She is very pretty all on her own; why does she need to be compared to me in that regard? She was compared to me a lot in karate too, because I was always at the head of the class; I had very strong basics and I was aggressive in sparring and picked up on things quickly so I always did very well, and while none of the other students got compared to me and found lacking, she did simply because she was related to me. So even though I'm coming at it from the opposite end of the spectrum, I actually understand why you would be a bit oversensitive about that sort of thing, and I highly, highly doubt anyone will look down on you for it.
For the record, I've actually never compared your dancing to anyone else's. I've watched a lot of pole videos, and you honestly have never reminded me of another dancer. To me that says you do have your own style whether you know it or not, because I don't see echoes of someone else in your dancing despite the fact that we're all pretty much doing the same moves.
I do copy moves as well if I see a combo I really like or some new floorwork, but I also try to think of my own stuff. For me, copying someone is the highest form of flattery; I would not be emulating their move or combo if I didn't think it was amazing. I really don't know why some people get bent out of shape because someone used the same combo as them. We're all a community, aren't we?
