Ok, so I made some "adjustments" to your photo, I think it looks pretty good. I will tell you what I changed and how I did it here:
Before:
- Added some shadows, I used the dodge tool however you can probably use your modeling program and just bake some shadows on the texture.
- Made the roof copper(ish), I took a nice copper color and painted over your bricks and set the blending mode to 'overlay'. Then I gave to that noble copper look as made famous by the Statue of Liberty, however since its not that old (or at least I assume its not) it wont have completely changed green yet, so i left some of it copper colored. Lastly I added a slight inner glow from the center to shine it up a little.
- Scuffed it up, In the real world nothing stays shiny for long so I added moss and grime to your model, under the windows, leaking off the roof and at the bottom. For this I used a 14 Pixel size splatter brush that came with Photoshop (I am sure The GIMP has something like it as well). After splattering the moss I smudged it with the smudge tool. For the grime leaking off I used a rust color brush, and painted a little under the brushes, the smudged it down, like it was slowly running down. Then having the active colors set to the rust and moss colors I ran the fibers filter to make it sort of rusty moss.
- I re-sized your windows and door, I couldn't actually change the size so that's just a red outlined suggestion.
- Lastly I added some cracks, not sure if you can see them but I used a 1 Pixel black colored brush and painted the cracks. After I painted them I added an downward emboss set to "chisel hard".
Final Result:
If you have any other questions as to how I did any of this just ask, I also saved the PSD if you wanna have a look at the layers.
P.S.
Make the clock part a circle, or else the hands wont fit right.
