Amateur 3D Architectural Model Post Processing~

please do excuse the nerdy title, just excited to share some work I did last night, helping a friend touching up a Rest House 3D model, constructed in SketchUp, rendered using Artlantis~
And the final tweaks were done by me in Photoshop, which is nowhere close to perfect but I had a lot of fun doing it.
Most of what I did is adjusting the brightness, colour balance, as well as adding some elements and ligthing using brushes,etc.
I made a total of 9 edits, but here are 4 I like the best, comments are most welcome :D
