16. Okay, now you can test the effect of the brush you made. Create a new file with a larger size, fill it with a darker background, then select a different foreground color and draw in the picture (you can press the square bracket key to increase or decrease the diameter of the pen tip. The left square bracket decreases and the right square bracket increases; you can also Adjust the opacity of the brush according to the actual situation in order to achieve the best effect), take a look, just drag the brush from bottom to top; the effect is not bad! ^_^ If you find a seabed picture to draw, the effect will be better !
