Great work adding in all the sidewalks. 

Here is a couple of suggestions. A roof features needs the layer=1 tag so that service roads can go under the roof. 

When you updated the name of the gas station, you removed the address. Those address are nice to have in OSM. Addresses are typically reused even when buildings are torn down. 

Both the roof and addresses have been fixed. I'll send you more info on OSM in a message.
