I'm using low opacity settings so the effect could be hardly seen.

Create another layer.



Tap just ones with the brush N 119 and erase back (consider that shadows too.)







Now this illustration definitely needs some text, so choose line tool and create a line.







Note the path settings near the content menu.

And just use type tool. Note to drag the type tool near to the path. This way the text will go in the direction of the path.







Now rasterize the text and erase it a little bit to fit the whole picture.



Use any king of pattern eraser.
