Absolutely stunning. This is way above my skill level, but two things did occur to me.
1) I hope you're adding more empty space around the island, so it doesn't feel so cramped.
2) Even though the lantern isn't supposed to have straight lines, it still doesn't look like it's in perspective to me. We're seeing the island from above, yet it looks like we're seeing the lantern from the side.
And due to the huge leaves and the smoothness of the branches and tree trunks, it reads more like a bush than a tree, but that's not a big issue, I guess.
