GrutBrushes Cloud FX are not stencil stamp brushes. These Photoshop cloud brushes are dynamic and responsive, n two brush strokes will ever be alike. The brushes respond to the individual pressure of each of your strokes of the stylus.
Turn your stylus into a spray can full of fluffy clouds. Pick one of the crispy Photoshop cloud brushes, press lightly for a slight whisp or choose a blobby cummulus cloud brush and push harder to blanket your photo in delicious thick realistic clouds. You can see I got carried away here but take my advice and rather take it easy, the secret to realistic clouds is subtlety.
