I agree with Chris and KingFury that you should dig out the cave a little more, maybe you could hang some buildings from the roof of the cave if you make the cave a little bigger, it would also look cool with some lava flows
When you think of a town in a cave. You really should make a more normal lookiong cave rather than just hallowing out an area like you have. Work with the cave shape and size rather than making something that could just as well be made above ground.
thanks guys yeah first I need to finish off the village buildings as I dont exactly know what dimensions it will end up being with the finished village, then ill get started on the cave aesthetics I cannot currently do any work on it for a few days as im away but when I get back it will be full steam on getting the village buildings done Thanks for the feedback!
