You look to be a girl on the beach who is having a good time. Nothing slutty about it. Since you have asked for critique, I can offer only one. It is a pity to see such a pretty girl with a bit of a muffin top. Spoils an otherwise overall hotness. I have to do daily sit-ups and crunches to keep my male muffin top under control.

Fun. You're on the beach in the pic so a bikini is fine. I wouldn't use it as a profile pic though.
