Adding snow to the rooftops

With the foothills adjusted, now it's time to winterize the chalet.…Let's push in on it, and you can see the chalet has a tiled roof we want to cover with snow.…I'm going to create a new layer and call it Rooftop. Choosing my Lasso tool by…pressing M on the keyboard,…I'm going to marquee around where snow would be on the roof.…The snow should have some dimension so it should go above the top of the roof.…Now I'm going to fill the selection with white, then I'm going to choose the…Brush tool, or press the B key, and deselect that area, make the brush smaller,…and I'm just going to paint where the snow would fall on this rooftop.…

I want to add some dimensionality to the snow by indicating an edge of shadow,…so I'm going to grab a shadow color from down here in the snow and this will…show where the edge of the snow would be on the roof. And same here: I want to…indicate that underside shadow for the snow.…My palette is set up for this project, so I'm generally just selecting colors…right off the plate.…
