This terrain lacks a decent background, for certain.
It also lacks a sense of nature, more civilization.
You'd think a gigantic floating thing like that would merit a little more...
Constructions and such surrounding it.
And, I might have been playing a bit too much Heroes of the Storm, but...
Somehow I just can't get the idea that, instead of water, you should use the
alpha tile under the floating thing and make some galaxy shizzle under
there, you know, like a dimensional portal or something, out of my head.
