Thanks for your comment
Mh... maybe I could go back and make some of the buildings bigger... I really have to admit that I haven't paid much attention to some size issues.
The scale of the close-up view is indeed 1px = 1m. You're absolutely right then, some of the buildings are very small, even smaller than 10*5m. I'm thinking about whether this is really not plausible. Even 5*5m are a not overly small room in which I could imagine a hearth, maybe a table and some places to sleep; if the building has more than one floor it would be as big as my flat
So enough to live in for a family. Especially as buildings of that size are mainly in the poorer quarters of the city.
The buildings which are smaller than that could be sheds, kitchens outside of the main building orbuilding extensions of some sort.
Does that sound convincing?
Nevertheless I'll check the sizes and may make some of the buildings in the northern part of Merridia bigger... that's no great deal.
I'll also do some research on city walls
Thank you, too, mearrin69
