8 Apply subtle blur
I’m not a fan of an image that’s perfectly defined. In my experience, if something is in focus, then everything else should be slightly blurred. I like applying the photographic effect of blur in different areas of a composition, because it helps the viewer to quickly home in on the focal point, and then enables them to discover the rest of the image. When I’ve almost finished an illustration, I take the Blur tool and go over certain areas using Gaussian Blur with a Radius no greater than 3.0 and a fade of 20 per cent. This leaves a more steamy feeling in the air.
