Ababar Stylistic Sketchy Paint

The principle of this application is very simple:
You upload a photo (from a gallery or a camera) into it.
The program covers the photo with a semitransparent layer with a texture, on which you have to draw, seeing the image below it.
Using a lot of brushes and special algorithms of the program, the usual photo can be turned into a highly artistic work, and then publish it in social. networks or send by mail.
