Elena, I do not see anything wrong with your profile. You are certainly an attractive woman. What I like about your photos is that you have a nice easy smile. To me, that very important because that shows to me that you are a positive person.

As far as what you have posted your photos, you posted what you feel comfortable about posting. Never say that you are too old, think of yourself as a vibrant 50 something woman who has much to give to the right person.
