What's your light set up? And what background are you using? You may be able to just change your light arrangement and use what you have.
You've got a great start! How many tries did it take? When I did mine own "selfie" about a month ago, it only took like 40 shots.
Thanks. I have a 47" Octabox as key, camera nearly touching my camera on the right. I have an umbrella to my back left for hair, and a bare speedlight right behind me for background splash. I am also holding a reflector at my waist for fill.
I think I got this picture in 10-15 shots. I was triggering my 6D from my smartphone that I was holding. Makes focusing easy too.
