UPDATE:
------------------------------------------------------------
I know I have to reach my "plateau" with Jinx, but I need to perforate more paper so I can flip the drawings. This next week I will.

It seemed a good idea to take one of the posters that John put on his blog the other day and trying to build better characters, caricature a bit and give them more life.
These was my observations from this poster:
Porky:- the cranium is really big compared to his little jaw.
- Body is little compared to his head.
- little ears
- little nose
- fleshy cheeks
- big eyes but not enough to distract the attention of the skull
- his tie is small
- he has a happy looking.
Daffy:- big cranium
- big beak
- little eyes but no too little to make it unappealing.
- long and skinny neck
- little body
- skinny arm and little hand.
- he has a happy looking too.
Now, I wanted to give the characters a bit more of their personalities, I made the line of action of Daffy more strong and I changed a little his expression of bland happiness to an expression of "happiness crazy,"Porky instead has an expression of happiness a bit more tender and a line of action less strong than Daffy. I also made the right arm of Daffy more visible, giving more space to the sillhouette of Porky.

This is my attempt. The car sucks, I know, I didn't give it much attention.
I think I could make the cranium of Daffy a little more big and give it smaller eyes for stronger contrast.
