SO! let's start with a 100X100 picture.
This is not really part of the tutorial but I used the blur tool to bring the (most awesome) character to the 'spotlight' of the icon.
1. Selective Colors:
Green: (there are 3 new points between the two that are already there in the corner.)
Group layers 2 (curves) and 3 (2 color fill). Set the Opacity of the group to 60% or however you'll like it.
Now that I think of it maybe it should be 80%. Just play with it til you'll find what you like :)
Ta Dah :D That's it.
If you have any compliment, complains, requests, and other stuff just leave a comment :)
