Georgian Architecture - 'The Perfect House'

This is a montage I made (in Photoshop) using elements of multiple examples of Georgian architecture (shot in Leamington Spa). The idea is to create 'The Perfect Georgian House', and make it as realistic and seamless as possible. At the moment, if you look closely, the seams do show. Note: The shadow of the pilaster was created by outlining a shadow (using the pen tool) from a similarly shaped entrance and colouring in the selection.
