I think if you are a wannabe cartoonist you need to approach it in two ways. 1 learn the principles and 2 experiment with youre own ideas and stuff. I am learning the principles on this blog and I made an other blog where I will try to put 1 doodle/caricature etc. a day. To get a sort of own eye and feel for things.
I did a new drawing of slabnernie. It's really not on model but I tried to experiment a bit, be a bit more loose. Uhm I think this kinda drawings belong on my other blog... Nah, I will use my other blog for own sketches and stuff.
