Step 1
Take your picture crop/resize etc. I found my base in this post.




Step 2
Duplicate your base and set it to Screen at 50% opacity.




Step 3
Duplicate your base again and set it to Soft Light at 50% opacity.




Step 4
Add a Selective Coloring layer with the following settings:
Reds: -20 / +14 / +26 / +4
Yellows: +38 / +34 / +26 / +30
Whites: +42 / +39 / -13 / -7
Neutrals: -5 / -1 / -1 / +1
Blacks: +23 / +13 / +4 / -4




Step 5
Add a Color Balance layer with the following settings:
Midtones: -19 / +6 / -12
Shadows: +11 / -9 / +17
Highlights: -9 / +3 / -1




Step 6
Add another Selective Coloring layer with the following settings:
Whites: -20 / -20 / -20 / -20
Blacks: +20 / +20 / +20 / +20
(I use this kind Selective Coloring layer very often to add some contrast to the icon, so I guess there are many other possibilities to get the same effect)




Step 7
Add a color fill layer (#B8D1FF) and set it to Darken at 50% opacity.

Step 8
Duplicate your base for the last time, bring it on top, desaturate it and set it to Color Burn at 10% opacity and your done.
