Avatar is the graphical representation of the user in social networks, forums, games etc. In other words, it’s his alter ego. Usually 2D-avatar is a square image which has a small size (100x100px, 64x64px). And that's why we should delete all unwanted items and keep the most important ones when you create it. Otherwise, it would be either difficult to see the details after size reduction, or they will make the image blurry.
