Okay, we're going to go from
in two steps. No lie.
Originally I was planning on following this tutorial
I made my base from this picture
and cropped it to where I liked it.
It's a bit dull so duplicated the layer and set it to screen 100%, brightening it up quite a bit.
This is where I started following the tutorial. I made the Selective Color layer and followed omg_its_olivia
's settings for Red: -100, 100, 100, 100
I liked the effect that had on my icon, so I just...stopped there. And got the above icon.
