My two cents is that 1. You're right, you can never control what someone else likes or sees in your work whether it's realism or abstract. And abstract is much more subjective than realism (obviously) because it can't be compared to the familiar. 2. But most people will try to see something representational in abstracts, like maybe a sun in this one, or stained glass here because of the bold outlines, yet this composition is good and balanced as an abstract. It is simple (in my opinion) and not as dynamic as say the Kandinsky you have posted.
You asked where the center of interest is on the Kandinsky, and I'd say it is left of center. I personally don't think there has to be one in abstract pieces. You bring up Pollock, and there might be one at times, somewhere, be it placed very subtly, but there may not be. I'm not a fan and don't like that my eye is all over the place with his work. I don't like his type of chaos. I don't like the "design" or aesthetic of his work. But I appreciate his language and his place in Art History.
The center of interest in yours feels also left of center, but also has a repeated circle right of center, so my eye jumps back and forth just a little bit, but the yellow one is more dominant of course.
I can draw about 50 abstract compositions before one that seems to "work." I'm totally self-taught, so my opinion doesn't mean much, but I've been looking at and studying abstract art for more than ...many decades. Since I was a kid. Almost obsessively. What I think works might be totally "wrong" to some academic art critic for all I know. I don't know "rules" though I've heard of some after the fact--after I've gone by intuition. It's hard to describe to someone else my opinions about their work, but I try to best I can in order to help them. Though, as you know it is all very subjective and a matter of taste. Purely.
If I say something is too literal (about an abstract), what would that mean? Maybe only I know what that means! That's what something might mean to me because I see a sun and sun rays. Someone else might see something else. It also depends on what you were going for to make a piece a success. If you want your viewer to see nothing at all representational, then that has to be worked on a little. Or maybe you don't mind it. Maybe it's inspired by those elements. It depends on your intentions.
Everyone will have differing opinions. It's your opinion that matters and other people can flitter off in the end.
