I lied, I'm a liar. I thought I had posted all the Tattoo Convention photos I wanted to but this one was half finished in Photoshop.
I've added some of the sparks on the right of the photo as they were only heading in one direction, I reduced the exposure on the crowd behind her until they disappeared and I've added a red-green-yellow colour dodged gradient which has added the teal and rose hints to the photo.
Gradients have been featuring a lot in my post production experiments, sometimes they're very obvious (example 1 & 2). Sometimes I will use a layer with a gradient map and they're a bit subtler (example).
I hope you like them all and my experimentation is working.
