Bucking Bull Head Illustration

Troubled Monk

Troubled Monk makes craft beer, soda, spirits and cocktails. We are looking for a designer to help us illustrate our newest beer. The beer will be called 'Seeing Red' and will show a personified (yet realistic) drawing of a bull head.

I am looking to have an illustration completed for a beer can. The illustration will be of a rodeo bull head, with horns. Styles of what I am looking for are attached under the 'Style' file names.
I want the bull to look somewhat mean (see bucking bull face samples) but I want the facial features to be personified (See 'Smirk') in a friendly/confident/challenging way. I want the bull to be saying in a friendly way ' I dare you to ride me'. The look shouldn't be too intimidating or angry, just enough to be playful.
I would be curious to see what the head looks like with a hat on, a piece of straw in its mouth, perhaps winking. The idea is that in a fun way he is challenging the cowboys to ride him. At the same time, it has to look like an intimidating bull!
I want this work to look good in either black and white, or colour (see color and illustraion samples). The color of the bull should be red in the color version.
Samples of what I am looking for can be found here:

Feel free to try something different if you think it will get across what we are trying to say - showing a tough, confident, fun loving bull that wants to challenge cowboys to a hard yet fun ride!
