I Found a New Drawing App Yesterday: ArtFlow

Here's what I did with it:

Digital sketches of decorative designs, hands, faces, and horned animal heads
A digital sketch of a radio with a bunch of construction lines, and a symmetrical face
A symmetrical digital sketch of a goblin-like face
Digital sketches of faces and facial features
Digital sketches of various humanoid creatures, a 13-eyed creature, and a winged dear head
