Nice work, I like the way you have achieved the streetscape with a different scale of frontage. Also kudos on the brick separator roof
My only critique would be that the 'Pet Shop' with a dormer roof just sits a little uneasy in that line-up. I would experiment with a further band of detail (a few bricks) between the 2 storeys or move it up the street next to your MOC modular and try to line the elevations through with that.
Other than that, great job
