Mix your photos
Don't make every post a selfie! To make your posts stand out they have to be different from one another and show a variety of your tastes.
Have someone else take the photo
On that note of selfies...stop taking them! In general, you look much better with a full body shot, and having someone else (with a steady hand) take your photo will look more professional. If there's a great hair day and no one around to see it, plug in headphones with the microphone that you can click to hang up a call, when you click this button on the headphones it will take a picture.
