That actually looks pretty alright! Try and work the perspective more, that hydrant looks pretty out of place. Shading is a good idea too! Good background silhouettes, I do buildings like that a lot myself.
Works better at night though, I'd re-do those with a brighter grey or purple to really sell the daytime element. Maybe some fog.
Also, to embed images you do it like so:
[img]filename.png[dashimage]
Obviously dash img should be /img, but if I do that it'll register all that as an image and ruin the example. The bolded bit is also important for making it actually show up!
