We could change the size there, but let’s use a shortcut. The brush is too big as we see here. Just press the left bracket [ to make the brush smaller. Press it a few times. Press the right bracket ] to make the brush size larger.
Press the left bracket [ until the brush size is set to about 30. Position it at the corner of the model’s lips, and we’re going to click-and-drag it gently upward.
By clicking-and-dragging then letting of at the corner of the lips, we’ve added a slight smirk to the model.
If you want to zoom in, try the Zoom tool or use the shortcut Cmd and the + or – sign (PC: Ctrl and the + or – sign). Press the space bar to use the Hand tool to move around the image as well. Now let’s change the nose slightly. The nose looks perfect to me, but let’s change it for learning sake. Choose the ASDASDSA tool from the left-hand side of the Liquify screen.
Hover over the nostril and click-and-hold for a second, which will make the nostrils slightly smaller. The key is subtlety.
If you don’t like the modified look, just press Cmd-Option-Z (PC: Ctrl-Alt-Z) to step backwards a step. Here’s a before and after look. In the first one the model looks more serious, and in the second one she has a slight smirk. Again, the key is subtlety, unless you want a cartoonish and unrealistic look.
Notice with this example, I created a slight smile with this model as well. But I also used a slight modification with the Twirl Clockwise tool, the third option from the top on the right-hand side of the Liquify screen, to not only lift her smile but twirl it a little.
