Apply zoom blur
I return to Photoshop and add a subtle zoom blur. This will give my art a sense of motion and helps to blend the textures and my brushstrokes. First, I merge the image on a new layer, then pick Filter>Blur>Radial blur, choose Zoom and set it to 10 pixels. I combine my zoom layer with the Masking tool: I apply a gradient on a mask, so only the bottom part is revealed.
