@Adder Haha, I wouldn't be too sure about that. Have you ever been chased by a territorial rooster who was trying to kick the bejeesus out of you with his fighting spurs? I have :(
I really like your use of negative space for the outlines and kept it clean and simple. I think it's especially strong on the green and purple shirts you posted in the link as the monotone palette gives it a softer feel for the bold design.
That is one awesome set of expressions. I do *not* like them on purple/green the way you did them... I'd honestly rather have the gray cat on the other colors... possibly a bright white rooster...you'd need.... what, 3 colors? red, yellow, and some pinkish shade at the cat ears, mouth, whisker dots(shouldn't the whiskers be white?)... but of the 3 choices, definitely grayscale. Still like the notion of the lineart with a few bold colors and a gray cat, or even a white one with a cute pink nose/pink ears.
