Hey there! :3

First of all, I'm going to talk a bit about your terrain. The majority of it is flat. You've managed to work around this however with the wheat fields, so it looks okay. However, to change it up a little you could include some slabs into the ground or above the ground, just to give it that little bit of depth on the flatter areas - not too many though, just a few.
I like the mountain in the corner, however! I'd mix some more block types in with the stone though - and I don't recommend ores; it's not too creative! :3

Secondly, organics. I really like your trees, and the positioning of them is great. If this were the next rank, they'd need some touching up, but for now they're good!
Future reference: Don't make your roots quite as thick, and make sure we can't see the different layers of the leaves! (I can see how you've shaped it, making a circle first) Remember you have world edit, so you can use a brush for them now!

Lastly, structure.
The water structure (with the fencing) is a really nice idea, and I can see you have an understanding of depth and detail. You have a basic frame around the structure, which makes it easier for you to detail. However, its normally a good idea to build the logs one layer out from the wall:

This just allows for an easier time detailing, and also looks a lot better.
I think, however, the positioning of the stone/chiseled bricks etc aren't really working with the structure. It might be an idea to rethink how you detail the structures - it's too contrasted and almost random how you have it now. The roof should overhang some more as well, I think. I think how you've tried to be creative with the shaping of the roof, but I'm not sure it's really working.
I like the smaller structure, however same with the roof - it should overhang some more.

Good luck!
