I'd suggest that the structures sit inbetween detail shots and silhouettes and that may have been what you were aiming for. But as an abstract, there is too much detail for me, and also, because the frame and building both appear to have 'hovered' into view (no ground to anchor them) they don't really seem to add very much to the shots. If the sun had been used to perform a more 'contra-jour' type shot behind the framework (creating a sort of light-halo), then it would ahve made more of a silhouette and perhaps been a stronger image.
As arclight says (and reinforcing my view of 'grounding' the image), if there had been something in the foreground to 'fix' the view.
That said, I see a strong rule of thirds which I would guess you aimed for, and you ahve also kept good detail in the sky without blowing anything out.
