Alright so I'm gonna start gettin involved, 
Is there a map happening?
Where can I see the collection of created stuff? 

Lastly the one thing I think most write ups are needing is the 'why'. Why are they or things that way. Unless a god has just dropped it there and told them to act a certain way it has got to have developed over time in their interest.

I think magic system and divine influence should be sorted before you are able to flesh out any races and their purpose.

It's easy to say dwarfs live north and elf south but a good world write up will tell you 'why'. How long did it take to mine out the hills, where did they live before that? 

Just my opinion...
