Coon the Cat
A picture that I took of my mom's cat, Sir Coon de Scampalot.
First I used Selective Colour, lighting him up a little bit.
I quickly inverted the picture.
Here, I used the Channel Mixer. He turned a purplish pink.
After that, I used the Vibrance. The only real difference was perhaps the sharpness of some lines, but I kept it as is.
This is my final. After the fourth picture, I started using several of the filters, selecting and changing certain squares after using the Oil Paint feature to smooth it out.
