Chocobo Concepts

These are five-second-doodles trying to come up with an idea for Frank's new chocobo tattoo. I have more ideas up my sleeve, such as a chocobo hugging a moogle, but somehow I don't think that'd make a good guy's tattoo.

Okay, the first one with the lightning bolt would be just black and white with dramatic shading. The second would be purely black, white, and yellow. The third would probably have bright popping colors, and the fourth isn't a very solid idea but I just wanted to draw an excited chocobo about to eat ghysyll greens. (However that word is spelled...)
