Clouds didn't end up being on my good side however since I got my tripod support thingy in I figured I'd take a night shot, shame my crappy camera could only do a 6 second exposure so I had to put the iso to 3200 and apearently taking obviously a photograph is a reason for the cops to try to run you over before they ask what you're doing. After I explained that I tried out my tripod and long exposure during nighttime they got to the point they asked if I took pictures as a hobby so I asked if they knew flickr which happened to be pronounced the same as 'fag' in dutch. They where not pleased...
Anyway, next time I'll try a sunrise shot (which is at the direct opposite of the visable wall) and some at later stages, then I'll bug you for the post processing since I'm really stuck on that part now.

E: Btw, the front of the wall isn't an option because there are really ugly studs placed there to support the whole thing.
Maybe I could try this one for a good night shot:
