I was unfamiliar with the source content so had to look it up. Eventually, I found the image off of which the stage is based. It's a fair work, but I have a few observations below.
-Love the water effect, the standing reflective water type fits the bill.
-Trees don't really blend well with the rest of the stage.
-You have a lens flare which is static, would be nice to see that animated properly. Though I'm not sure why there would be a lens flare. Rays would probably be more appropriate.
-No shadows for the obelisk or trees seems odd, especially with the lens flare.
-Overall it just lacks depth and positional relativity.
It's a decent stage and I'll keep it around but I really hope to see some updates to this as it is a really good idea and setting in general. Thanks for your work!
