In Oss Hugo and I have been promoting our 'digitable".
It's always good to excercise. Making digital caricatures isn't very easy, you don't have the same feel, touch with your equipment as non-digital. A cintiq sometimes feels like glass.
But it becomes more and more fun when you feel you're getting in control.
One problem is: the light from your cintiq can sometimes blind you, so you don't see your model very clearly. Another one is the huge amount of buttons, toolbars and other device that makes you slow down.
You might say: then why even try?
Well, I like the challenge. And I believe it's a very funny mix between technique and creativity.
