Even before you watch, I want to tell you that this tutorial is for beginners.
The same technique described in this video can be used for drawing in Adobe Flash too. Of course, there’s little difference in Pen Tool but principles are the same.
I remember how life was hard before I could afford Pen Tablet but then I finally learned Pen Tool in Flash and life got easier.
This tutorial is really good at describing how efficiently you can draw with mouse in Adobe PhotoShop if you don’t have a pen tablet.
