A nice map for miniatures.

An option to empasize one thing (like the alley) while providing extra details (like the interiors) for "just in case" would be with a graphic hierarchy.

One example might be to leave the interiors as white lineart or greyscale, while the alley is in color.
A subtler way would be to create the interiors as a pale color layer and the alley as a bold color layer, making the difference between the indoor and outdoor spaces 'pop' visually.
