I think it is fine as is. Just tell them it was for symmetry, so the small picture was facing the main picture.
As for being lefty, it has not caused me problems quilting, only when I was trying to teach 2 of my daughters things like hemming, hand stitch and Xstitching. I always start from the opposite direction. Daughter # 3 is also left handed so no problem.
My dear FIL philosophy about being left hand was that everyone is born left handed. You only become right handed when you make a mistake, so left handed people have not made a mistake. Guess which hand he used.
