This Angel icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
The Angel icon is composed of a circle that appears to be a smiling face. There are two small round circles for eyes and one upward curved line for the mouth. There is also another circle that forms a halo at the top of the head.
