Color Reduction

My idea was to make the picture stange, you can think many things about the picture.
The process I used was: I edited the picture on Be Funky. After I printed it, I colored the back of the paper black then traced the different colors white and green. Then the parts I didn't carve out was the black.
I would've liked to cut the pieces out and make it like a puzzle. I like how different this picture is, I love poems so I could write many poems about this picture. I love how it's like a stamp and you can wash it off if you need to change the color like you'll see in my other post.
I would like to learn more about printing color reduction.
