YO!!!! If anyone would still like to help.
Would possibly, someone be able to make this model look more decrepit and broken? As if something had a difficult time smashing through it. (This link is a download for the mod/materials)

(I couldn't tell which prison material went with this specific model, so I just included them all... whatever texture looks nice will be appropriate, thank you.)
This is a crude example that I made in hammer of what I was hoping the final image would look like.
Would you also be sure to make the model in 2 peices, like the example here? (So that I can easily space them as need be) It would be a big help! Thanks in advanced!
