Art faces

I have been working on my self portrait. I used the chrome book to take a photo. Then I went to pixlr express and I choose the effects I wanted to used. This is how to do pixlr .
Step one: take a picture then go to google and write in p.i.x.l.r
Step two: Go to pixlr express. Click on it then go to collage.
Step three: You will see four squares and move your mouse to the square and you will see a plus click on it and find your photo.
Step five: When you download your photo you will see a arrow click it and go to effects and go to atomic and choose any colour you like.
