dvation,
welcome to
RP.
this is the old story about the difference between a 'shot' and a 'picture'. a shot is just any old thing that really doesnt say much or do anything by itself. a picture is about the old saying, 'a picture is worth a thousand words'. it says something. it maybe tells a small story or something like that. 'shots' are often used in montages or collages to create a more full picture, tell a story, but by themselves they do little.
you've also got a couple problems with the image itself. mostly, the whites are blown out, giving an unkind glare to the image. this detracts from the color and geometric interest. and the other thing is the angle, as someone else mentioned. it's straight on. had you taken this from a 45 degree angle on one side or another, i think it might have been better. even taking it up higher or lower might have worked, but dead, straight on tends to say 'this is a shot' and not a 'picture'.
and one other thing that might help with an image like this is a bit of contrast. and i dont mean contrasting colors or light here; i mean something else in the picture itself to give the eye something to contrast against. it wouldnt have to be anything large; a tree branch, a bird flying by....something. even a person behind the glass would have helped. the old 'rule of thirds' somewhat applies here and that old rule works because of contrasting objects and contrasting the images within the picture.
i'll give you an example. if you take a picture of a penny, straight on, dead center in the shot, and close up, it will be so-so. it's just a shot. if you move your angle off to the side a bit or lower the top of the penny down for a big perspective shift, it gets better. if you then moved out a bit, put the penny off-center in the image and added some shadows and highlights, it gets a bit more interesting. if you then added some other object in the image, say a fly flying by off in a corner, you've now got some contrast by object. this last one isnt as crucial as the others, though.
basically, your image says 'here's a sort of interesting geometric pattern in a building'. ok, that's fine. it's a shot. it does say something, but it's like it's not quite complete yet. it needs something else. with the glare cleaned up it would make a fine addition to a montage. but by itself it just doesnt quite stand up. even if there were an interesting reflection in the glass it would be better.
so, basically, what you've got is a foundation here; a foundation that now needs something added to it. and that's really pretty much it.
