Results not good – Camera Art FX - Real time effects for pencil sketch, comic, watercolor, grunge, poster, doodle, cartoon Review

I got this app because of the pretty line drawing in the screen shots. Tried to get a result similar to that line drawing, but couldn't. The lines are too dark and there is no preview, I deleted this app.
