During a conversation about categorizing art so that our terminology would be more specific, my friend agreed that the term "abstract" was just way to inclusive. For example, the image below would fall into that category and yet it's still realistic enough for us to completely comprehend the subject matter. It's got the flavor of impressionism, yet it's done in a newer version of the pointillist style.
Angelo Franco's oeuvre is an updated version of pointillism and he bends the rules just a bit sometimes to suit his needs. The results are bright and postmodern. You'll find lots of images to study at his Web Site, where he puts his Artist Statement front and center.
