Here's a rough 3D mock of how i imagined 2 parts of the city being - the Merchant & Guild Quarters (though 'quarters' might be switched out by something else depending on the kind of vocabulary i choose to use in the world). Merchant Quarters are where most shops and bazaars and such are, where as the Guild Quarters are where guilds and things of that sort are located (a lot of quests originate here).
This is just another angle of the work thus far...closer up just so you can get a feel for the size of the dividing inner-city walls and the larger outer wall. Its all just quick concepts and such right now...so a bit of this might change (or just get greater detail).
Here's a quick mock i made of archives before working on the town layout - just setting out basic shapes to get a general feel for what may or may not work in the long run. Size/details will definitely change as i realized some of what's in the picture won't really work in the end...but the overall 'feel' will kind of be the same.
