Hey there :3

So first off I'm going to talk about your terrain. It's completely flat. The only attempt at terrain you've made is spamming bonemeal around the grass - Not a good tactic. We look for creativity on this server, and spamming bonemeal certainly isn't that :p Even a couple layers of grass can account to terrain, just so long as you don't leave the plot completely flat. The only time we allow that is when you have an amazing building on top of it.

Speaking of, your structure. It's a nice start. It has an interesting shape, and what you've done with barrier blocks is impressive; I know how hard it is to work with them, as I tried myself once. That being said, you have no detail on your building whatsoever. You have little depth - the only depth you've created is from making the building have multiple layers as it extends upwards. And the only detail you have is at the bottom, which is far too repetitive and simple. You have no layered depth, you need to change this! It helps to add a frame to your building; it means you can add detail and it fits with the shape, instead of just pertruding outwards.

Lastly your organics; the trees. Too small, too basic in shape. I'm sorry to be blunt like that, but there's no point trying to tiptoe around the problem. The leaves are too well placed and not random, same with the roots.

Good luck!
