that's a nice start, when you put more into it i will be able to get a better sense of scale. However I must ask.... where did the water go? I started thinking about how long ago the water dried up, and how much water could be spread out around from Rain fall and then started to think were is the water to for clouds.... polar ice caps? or heavy rainy atmosphere where the water is in the air and slowly comming back down... eventially forming lakes on the bottoms of the oceans... and new cradles for civilization in the oceans... i dunno... maybe i went a little far
