These buildings are tagged incorrectly

I think this motel is not places in a good spot in terms of realism and profitability

Real names are not allowed as street or are names. Please rename these roads and areas

Are all of these walkpaths beween roads and houses for private use only?

This mall is incorrectly tagged

These roads are really close together. If you wanted to make a cul-de-sac (see image: https://t.ly/OAnXs or image: https://t.ly/Irp6h) you should tag a point as “highway=turning_circle” or “highway=turning_loop”. This gives the same effect, but it is the standard and also looks way better. Also, it might be a good idea to put more space between the roads if you want to have buildings on those parts.

First of all, real countries don't exist in OGF. Second of all, these buildings are literally just boxes. Also, the buildings touch the roads.

This junction is very messy, and has very tight corners and the bridges are very short. It kind of resembles the other exit. If you want I can help you with this.

I noticed that all roads are unclassified, maybe it's better if you specify the road that it is. For example, roads with houses would be 'highway: residential' and if they were important roads for getting through the city I recommend you use 'highway: tertiary'
