Overall I don't think I'll be using the Prusa beyond simple details and more functional tools, but its still pretty decent for stuff that isn't right up in the foreground. Some of the more obvious lines in the this structure will be covered when more details are added.
On my monitor, that reads like brick or block "telegraphing" through a layer of stucco on an old building. I sometimes spend a fair amount of time trying to do that on purpose, so I would see it as a happy accident. I would think some weathered off white paint and a "ghost" sign, and you would be well on your way to a nice building.
