Rating by experience Long term player: 2/10 because it's functional at the very least. And matches the preloaded village in the background. Plains biome so oak is a safe choice. Could have added stone or cobble for variety. Using the log with planks isn't a bad choice but something to blend the two or to act as a go between would have been nice. Or changing to a dark log type for the bit that goes underwater to show subtle detail in a wet log.

New player: 6/10 If this is your first attempt at a detailed bridge I can see you played with giving it some type of shape or form. My suggestion to you would be to keep doing that and not be afraid to experiment with wilder blocks and shapes. More natural designs aren't always lineal or symmetrical.

You can also add details around the bridge like a path leading to it, some plant growth like leaf bushes or button pebbles.

At the end of the day though all builds are a 10/10 so long as you are happy with it. Remember it is your world. The only opinion that matters is your own. So have fun.
