Thank you for the comments! No new picture yet, had to find some sleep as well
But as to those questions:
The cloister is a kind of religious building, but this country doesn't have a classic monotheist religion or something, it's more like a kind of animistic religion (worshipping spirits of nature, ancestors and such), so this cloister is called a "hermitage" and is run by lay people who come there for a time to find inner strength and be close to the spirits (part-time buddhist monks, so to say). Since it is a bit more complex than just the average house, I've postponed drawing it and want to put some thought into the general design of it first (what kinds of buildings does it need?).
The buildings are quite easy to make (I'm not good at free-hand so I have to resort to these measures...). They are drawn using the line tool in various widths and a second layer for the roofs. I'm pretty sure there are more beautiful ways to do them, but I don't have the dexterity for it.
If you are really interested in it step-by-step, let me know, then I'll write a quick tutorial.
