Build Relearning On Worldedit [terrain][half Build?]

Hello guys, it is me MrCoffeeTime here just wanting to show you guys some of my most recent work on minecraft involving one of the most juicy mods known as WorlEdit. I am still learning and am barely using the basic commands to make some terrain.

The first screenshot [The crops and icy mountains] was where I started and tweaked with some stuff, I advanced more on my other build [Hidden Valley /Entrance/]. I name it /Entrance/ as I really liked that piece and will probably add more on to it.

I know this isn't much but here's what I have and I'm proud of it. Please give me feedback and protips as I really like doing this kind of stuff and want to get better at it.

Note: The tree has been a pain in the ass right now as I don't know how to keep those darn leaves from decaying on my beautiful world. Please give me a tip on this guys.

Extra Note: I Used shaders on some pics because I thought it gives it a good look although I'm not much of a shaders guy. I'd appreciate it if someone would recommend me some good not too heavy shaders.

Omg since my old laptop had everything I built from months ago , I thought everything was lost until I saw I had everything saved on my mediafire account!!!!

 

Looks Interesting. After Corkus, who knows what your gonna pull out.

 

Lol maybe I already am working on something big? e_e or am I....? hahaha no, seriously... or am I......?

 

the icy mountain base is very kinda weird, and has a flat line running across where they all go up at once

apart from that, nice use of the

 

Yeah like I said before, the icy mountains where mort of me discovering how to make stuff happen lol.

 

You should try to use voxel for your terrain, really makes it easier! Also try to add more details, grass and a few trees... and buildings like houses and such ;)
As for the leaves on your tree, I have had the same problem before, just set the leaves to be of id : 18:8 (for oak).
Isn't there a gamerule that controls that?
