Your still working at this abstract millarky.
It has potential.
To me it looks a bit flat, what I mean by this is, it all seems to be the same tone of gray.
Have a go adjusting the levels to get some more shadow in the structure and brighter highlights in the sky.
I would also crop the left side from around the angle at the top of the main arch, as this side of the structure over powers the image a bit.
Keep working on it mate, your getting there.
