Ally, background for a comic or a cartoon

Ally, background for a comic or a cartoon - student project

I have struggled a little with the placement with windows and doors, and how narrow/wide, low/high they must be for it look realistic, thinking it is easier to look at a photo of a street with regard to the placement. I have drawn my own idear of an ALLY, thinking it could be in Morocco.

I have been looking at reference photos and paintings from Morroco, to find the color-palette and has also placed watercolor texture from a photo on the drawing. Thinking this could be a nice background for comic or cartoon.
