Wintering original plates - TV campain scenes

2D Digital matte painting work on TV scene for winter campaign beer advertising ( Peroni - U.P.P. studios)
My task was to add heavy snow banks on roofs, cornices, walls, doors and windows frames, balcony, etc. to have a look of a fresh snowy morning, after snowstorm.
Project needed many photo refs (Quebec is perfect for big amount of snow) :)
The ground was created in 3D afterward
Also, some backgrounds needed to work with adding pre-adjustment blur while painting (to match original plate background) See two last shots.
