My "Java Robot" above was created in Photoshop.
I started the sketch very loosely, just enough detail to
indicate expression and what he's doing.
Later, I added the color loosely and still very little detail.
The maximum amount of layers I use in Photoshop is
usually about 2 to 3. Once I like what I see I just flatten
all the layers. I like to commit to the image just like you
would if you were painting on canvas.
Enjoy:)
