This is my finished work. Unlike my usual workflow with heavy postproduction, I had enough time to complete most of the elements in the scene. I mostly did leveling and toning, to give the image more natural and warm look, enhanced depth of building volume, added atmospheric effects.
Because the upload is allowed in low res, I attach several partial views and comparison of Raw&Finished work.
Thank you again for organizing this interesting and exciting challenge, it was my pleasure! My best wishes to all the participants!
