Brief update.
Puddle getting permanent recognition status due to popular demand.
I put in a run of the mill road, changed the shop sign colours to lime and the shop's ground floor from LBG to white so it contrasts with the second floor's grey. Think this looks more realistic.
'Planted' a bending scrawny tree / tall bush in the side passage and did some other small tweaks.
I'm hoping to find the small window panes in reddish brown so I can make some look boarded up. Not sure they exist, will need to check on Bricklink sometime.
