This last month my wife and I adopted two kittens from Forgotten Animals of Los Angeles. They're a terrific agency that rescues strays and finds loving families for them. What's nice about FALA is that they take the time to find good people to match to the animals.
Since then I've added kittens to my cast of characters for Squaremania. I wanted to do an illustration of these kittens and this is what I came up with:
The two kittens in the front, the twins, are based on the ones we adopted. They also had two brothers (the grey kitten and the orange kitten in the back of the box) who were adopted just today.
I do the cleanup in Adobe illustrator. Then I paste it into photoshop (keeping the vector lines in tact) and when the painting is done I go back to illustrator to 'self color' the lines.
And these are the combined color layers in Adobe Photoshop. There will end up being one more layer when I add the background into it...so far it's just the characters (and they're floating on a blank whiteness...):
