I found this site named Drawing How To Draw that gives step by step instructions for drawing your favourite animated characters.
|Phineas of "Phineas and Ferb" (mine). Timmy of "Fairly Odd Parents" is by my son Damon.|
The site also has lessons on Art Principles, Landscapes, Mediums and Methods. There is an option to draw online and you can also participate in drawing contests. It's an extensive site.
