I can't see much. Just some very dark, almost black foreground, some heavy gray rainclouds and a patch of white where I think the sun is. And a slanted building in the right. The low lighting makes it very hard to make out any detail. Could be just my monitor though.
I think your sky looks neat, with the brightness breaking threw the clouds. It may have been clearer if you walked past the building on the right and aimed your shot higher a bit (this may have taken some of the other distractions away). Thanks for sharing.
I like the shot. I've shot a few like this myself and it can be a little tricky getting the lighting just right. Try playing around with the shutter speed and a tripod (if you didn't use a tripod this time).
