Hammerhead sketches

I then moved onto the Hammerhead hairstyles, and as they character has a flat head I wanted to portray this in the hairstyle, I have drawn a number of sketches to relate to this idea.

 

 

I was also thinking about the Hammerheads neck, as this is wrinkled for when they expand there neck, I thought about having black lines around the neck like the image above, but this is just an initial thought and I will develop this further. I also thought about having black straight rectangular eyebrows to go with the square hair.
