And we had to cour, pattern and tone it. Here are my works:

My set A : Pattern
My set B: Tone
Actually when I did this. I actually didn't know that we are mostly supposed to used black, gray and white. But instead I really did toning.
My Set C: Colour
I thought mine was a little too colourful. I think I should actually just use a few colours and not this much. A mistake of mine, unfortunately.
