Do I need braces? (Picture)?!

It doesn't look too bad to me. Ultimately, your the one who has to wear your teeth and deal with them, so whatever your comfortable with. I myself have braces as of now, and get them off in a few months. I'm personally really glad i got them, because i noticed such a huge change. If you think they'll bug you later in life, you should just fix them asap.
Hope i helped.?(:

Personal experience.

your bottom teeth look fine but the top ones might need work
