There are several ways to improve your skills on architectural visualization, but practice is one of the most important aspects of fine-tuning your technique. If you don`t have any projects designed by yourself to practice, you can always find some classic buildings with tons of information available on the web to exercise. A couple of days ago an artist posted on Blend Swap a full model of the Barcelona Pavilion from Mies van der Rohe. The model has 23 MB and was all rendered using Blender Cycles. This is a nice example of a classic building that could be used to practice modeling, rendering and post-production for architecture.
