I would like to know how you do the shading so well in such a short amount of time MC.
I have no idea how long it takes me to go from sketch to finish. What I normally do is draw a quick 3 minute sketch in Flash (like the one below) and then use alpha on it. Create a new layer and draw over that. And sometimes, if there's a lot of colour to be used, I make more layers on top of that and delete the lower layers.
If I carried on with the one below, there'd be a 'not finished' period where I wouldn't be able to show it until I'm happy that that stage is finished.
And so. Three minutes.
