In this I have shown How to create an Raster Cartoon using GIMP. This video is not about the vector cartoon.
Difference Between Raster and Vector is that when you zoom up the Raster Cartoon it will be pixelated while the vector is not Pixelated. In future I will be Creating Tutorials on How to create Vector Cartoon.
While GIMP is the Open Source Software Everyone can use it and easy to use too :). It is the Perfect Alternative for Photoshop.
