A quick word on scenery...
Becca lives in an end rowhouse. There are three steps up to the front door from street level, though the house is set back from the main sidewalk by a small front garden. The garden wraps around the three open sides of the house (right wall shared with the neighbor). The garden is largest in the back and the side garden ends on a small alleyway. The house is red brick with a black door like
this one, only with a brass knob, letter slot, and lock, and the other difference being that the door is black. There's a black iron railing on the steps. All of which works with what Firefoot has written, since I'm sure that garden includes a lawn.
Cel is feeling detail oriented. And very visual.
