Choosing an Icon to Represent My Art Portfolio

I'm preparing my portfolio, resume, business cards, etc so that hopefully I can start applying for internships soon. First thing to tackle - design an icon or logo or something that represents my work (3D character modeling). Here are some of my options:

1. Status Quo

This character model is okay. It's simple in design, color and expression. But the wireframe topology is unacceptable, so I won't be able to display the detailed work in my portfolio.

2. Badly modeled giraffe

Probably too complicated to go on a 3.5 inch business card. Again, wireframe topology is terrible. (It was modeled in CMPA 110).

3. Creepy Self-Portrait
I expected this modeling project to be a glorious achievement. But unfortunately, it fails to resemble me. It is also quite creepy to have a floating head on a business card.

4. Janito

Janito is a simple character that should fit nicely on a business card. I have the model done but I still have texturing and rigging to go before it can be presentable :(

5. "Rarrw!!!! I'm a scary scorpion!!! Hire me or... rarrrrrw!!!"
