I like the sky,its beautiful!
the terrain is not bad but isnt your game not too jung to show?
Try to end a part,like a town(for sure there will be one) and when its finish the way you want it then show it and for sure you will get better critics.
About the storyline: i like it!,sounds like the storys of those nice snes rpg games that i liked and still like
games.
but if the people just disapear in the middle of night and you just walk with a camera..well..would it not be a little bit too boring?
try adding more details to the story like:people disapears and strange creatures came and soo on,our player will have to fight his way trough monters and undefined creatures to find the true and how many levels will there be,how will the game looks like wich featus you are planning to integrate etc etc.
its just too little what you give to comment.
The goal is not to make something and ask for comments but to end something AND THEN ask for comments
