Here are two layouts. The first had to use one point perspective. The second had to be an interior using two point perspective.
I did this one all digitally. I sketched it from a thumbnail and then cleaned it up and added some grey (assignment had to be colourless). It came out alright. Kind of a Popeye era NY meets a western sort of background. I'm happy that it still feels organic. I used some grids for the perspective, but drew all the lines by hand.
Interior two point perspective. Blue pencil sketch. Digital is okay for some things, but I have better control with pencil and paper.
Added some value digitally. This method of colouring worked better than the last one.
It's the interior of a pirate type room by the water. I like the clutter of this one. Feels lived in.
