Almost 10 years ago I did this matte painting for a friend's Short film, after some years I re-worked on the comp and added some nicer FX smoke columns.
Inspired by the old school matte paintings look and overexposing on purpose to get that Albert Whitlock's style.
Done in 3D for some buildings destruction, photobashing in photoshop and final comp in Nuke.
