Maybe make the green a bit darker. I get that you’re going for grass and a river, but that’s conveyed with any green, and I think a dark green would go a lot better with the lighter blue.
As another commenter mentioned, the river would be better as a simple diagonal stripe. You don’t need a complicated river shape to convey a river.
This may be limited by your drawing skill, but I think the emblem should be more complex. Right now, it’s in this area where it’s not simple enough (i.e., it’s not just a flat, one-color shield) to match with the rest of the flag but it’s not complex enough to really feel like an emblem. It stands out but doesn’t quite have the complexity to warrant it, if that makes any sense.
The emblem might be better off in the middle, left, or upper left. Symbols on flags tend to go there instead of on the right, where it’ll be flapping in the wind more.
Updated it a little😁
The grass is more dark,
I simplified the river, didnt made it a strip because I want it to convey an island.
I moved the emblem to the left, someone else said to make it more simple, but I dont have ideas
The new green and the emblem on the left are definitely improvements. While I get wanting to convey an island, I think you could still do that with a more geometric shape. Maybe a stripe that splits into a circle or diamond in the middle. If you’re going to have a line going diagonally across the flag, I think it’s best to have it be simple and geometric.
I like the concept, but I have a few suggestions:
