To take cute pictures, you have to learn what are your best angles, and where the light hits your face. Now, this may sound a little conceited or self-loving.. but you have to spend at least some time in the mirror posing, and taking pictures of yourself.
If you have a double chin, make sure you're not looking down.
Everyone has a "good side" unless you're lucky and born with TWO good sides. *Bitches*
The "arm pose" is a great way of hiding fat arms. You know, when you pose with your arm on your hip. Make sure your fingers aren't doing something weird though because sometimes your fingers can look amputated or claw-like.
Practice smiling. Sometimes your natural smile isn't cute.
That's all for now! Hope I didn't come off as bitchy!
