I really think this is better, still without text. It's something between ridiculous and cool, which I think equals amusing. Does the red "fire-line" work?
I've been thinking about making the duck smaller on the shirt as well.
I much preferred the duck in the egg in the stomach to the fire, but I like the colors on the second one better. I like the black and the green t-shirts.
However I do think the second version is better. I will consider the text, but thanks for your input. If there's gonna be any, it should be smart enough.
Thanks.
