In fact, I'm not sure to understand what you mean by "meaningful" :scratch:
That's the catch with "abstract" in photography; you find the form, you don't create it. Something drown you to it, it could be anything, even just a pleasing shape or proportions of colors or tones. You should know it, otherwise is just lucky shot and "lucky" doesn't constitute as an art. Here comes the AA idea of "visualization", clear idea comes before triggering of the shutter. Otherwise it is just a "sharp picture of a fuzzy concept"

. Pictures like this have a wide range of interpretations. Some will like it, some don't, that's normal, some will "attack" and is good, to have a few words of defence better, than just "you don't understand me"

. Most of your pictures I've seen are strong images because are relatively easy to interpret (not all), the form however is as a rule pleasing to the eye. This picture I find untypically cluttered with too many elements and not that aesthetically pleasing.
