Is that your regular bite? Can you close your teeth closer together?

It doesn't look as though you NEED braces, but you could benefit from them.

It's best to have your dentist decide this.

I had very straight teeth but I had an overbite and needed braces to correct that. It's not always about how the teeth look. X-rays will help your dentist determine if braces are needed.
