Choosing from three different photographs

[Lauchis]

Hi everyone! This is my first post ever here, and I'm actually in need for some help =)

One of my classes in University is holding a small inside photography contest (it was mostly a way to keep students busy during winter break) in which we have to present just one picture, and I'm having trouble deciding which one to present!

Here are the three pics with their Exif data. All shot with my Sony DSC-H50


Some brightness and contrast adjusments done
Exposure 1/1250
Aperture f/2,8
Focal length 7mm
ISO 80
Flash: off


Brightened with curves, and corrected the colours with selective coloring (mostly the white)
Exposure 1/1000
Aperture f/4
Focal length 46mm
ISO 80
Flash: off


Zero editing in this one
Exposure 1/320
Aperture f/4
Focal length 51.8mm
ISO 80
Flash: off


Which one do you think would have more chances in a sort of amateur (but not really, since it's an audiovisual oriented career) University photography contest?

I'd appreciate any input at all, both on the pictures and on the post processing.

Thanks in advance!

I like the third one the best, but it needs some post-processing to really make it work; it's a little dark. It would work well in black and white I think.

The first one is well shot but a bit boring and the second one is good but needs the bit of wall to the left of pigeon/pole editing out.

for me it's the second one, but I agree with the person above that the small part of wall should be edited out

Thanks, guys, I ended up doing what you said: edited out the building from the second picture =)
