Hey there! :3

Firstly, your terrain. You have some nice terrain - a good cliff, and some nice variation. I also really like the wheat area :3 You could decorate around the outside of the pond area similar to this: https://imgur.com/a/U0Eq0#0

Secondly, organics. Your trees are looking really nice! Some of the leaves are looking a little weird, however. You can see where you based the shaping of the leaves with the circles you started with. Remember, you have world edit now! So you can use a brush for the leaves. Remember to include a high air percentage, however.
Eg: //br sphere 10%leaves,90%air

Lastly, structure. You have way too much detailing on your structures! It all looks a little messy, with the palette choice, and the logs, the roof etc. I wouldn't use stairs for the whole roof; I would use full blocks. The chiseled blocks don't work with the oak wood, use a less contrasted palette.

Good luck!
