I see this is your critique gallery and you haven't posted a daily today...yet. So I just wanted to say that this is is nice...I 'd love to see what you do with it per the other suggestions below. I think the shadowing is quite interesting...like it.
What would make this work perfectly is if there was either a hint more detail in the shadow side of the SQ or...
a rim of light on that side shaping the darker side out.. ( the rim would only be possible in a reshoot) I do not think you could PP
a rim of light in there.
