Architectural Modeling

So lately i started to mess around with architectural modeling just for fun .Of course Blender can do that too!
Here are some images .
external view (attached with internal) ,internal view(attached) with Yafray,the others with Kerkythea.


The first two are good but the third one is the best. The first one looks washed out and the road looks flat but from a technical stand point, I guess it’s acceptable. The second one needs some AA and the third one is just needs abit more resolution on the textures.

i have started to model in architechture… i am having trouble rendering internal images… help would be aprrecieated
