This sounds interesting. I have done quite a few building maps. Could I ask for more information on what type of map you are looking for (photo-realistic, hand drawn ) and what level of detail are you looking for?

Even if I am correct, I would still advise you to follow your heart. This whole Cartographers Guild thing, it seems to me, is more about passion and skill and learning new techniques than it is about definitions and rules.
Hand drawn is perfectly fine. Whatever floats your boat.
Same goes for detail. I won't need things like furniture placement and the like.
I really just want something fun and different while at the same time fitting in with the medieval theme.
