Nice work on the modeling man.
Since you took your time to build the whole roof structure I suggest you show it.
It's a nice piece of architecture, use it! Make the top barn door stand open or something, or make it miss a piece of roof?
The lighting/shading/rendering I guess has to be seen composited with a little grass or dirt "floor". Floating like that, it doen't say a lot in my opinion.
Keep it up, and keep us posted!
Always up for a chat !
