Adding repeating details to the walls

In this section, we're going to add…some repeating decorations to this lower side wall.…Each decoratoration should fit right between two crenolations, so…let's start by adding a new layer for the guides.…Call it Wall Details, and with the brush set to…20%, draw straight down the tip of two of the crenelations.…I also need a few guides for the top and bottom of the…decorative curve.…

Let's add a side line for the decoration.…Then draw the left side of an arch,…Lasso around it and copy drag duplicate it and transform it negative 100%.…I'm going to erase the top of this to even it out,…then with the lasso tool lasso around the arch.…And then copy drag duplicated onto another layer.…

Hide the selection and let's copy it again.…Notice we're copying these arches flat. They have no perspective added to them.…We're going to rely on Photoshop's distort tool to do that for us.…This is the same technique we used to create the crenelations,…taking one form and duplicating it to get a uniform pattern.…(BLANK_AUDIO)…we'll be distorting this side down.…
