Pfew~ This one took some time, sorry about that !
I'll try to tell you a bit about the process here, because I think it's pretty fun to do !
First ! This artwork was separated into 2 big parts, The 3 characters in front in their own "set of layers" (a file to be simple) siting in front of the second set of layers containing the close up, this helped me to not have to worry about overlaps.
Then I made different separated masks for a faster workflow, So what's in blue are the characters (I did the same for the close-up) And the red is obviously the background
Then I separated each character using masks of their "main color" so Pink for Cupcake, gray for Arre, and that less saturated pink for Mawnshee, that really helped me to work on each of them, because there was a lot going on.
After that, it's pretty much a smooth sail, making each fur/skin-patterns for each characters.
I then focused on shading the most remarquable parts, so basically the wettest parts yup x3
And once I was done with that, it only took me a day to do the general shading, so
Main shadows > Secondary shadows > Main lighting > Tertiary shadows > Secondary lights > A nice vignette around the frame (but not covering the close up) > Color correction (+ Some more saturation)
And voilà !
A delicious piece that should satisfy the kinkiest of us ;p
