Pinky and Spiky: Difference

I found an old notebook, and I decided to use it for my comics of Pinky and Spiky. In this way, they will be compiled together easily. I can always look at it when I have a free time.

In my comic, Pinky and Spiky are stating their traits/physical appearance to show their differences with each other.

Pinky have snout, she is a pig, and color pink. While Spiky is a hedgehog, color blue, he have spikes.
