That looks good man. But what do you mean by cockeyed? Do you mean the back of the island being higher in elevation? I liked that part of it too. It made me work around it and I made that elevated area a throne room with lookout towers on either side. Yours looks similar to what I did. Also it always faces the sun.
Cockeyed: Lopsided. Askew. Uneven. Asymmetrical.
When you look at the island, from the direction of the bridge, the left side of the island is lower than the right side of the island.
When I started laying floor tiles, I started on the right hand side of the island and the more I built towards the left side, the higher off the ground the tiles were, until I reached a point where I could place one of those low wall castle tiles underneath it without clipping through the ground.
If I started from the left side, the floor tiles would get buried in the sand about halfway across the island.
Building from front to back was the same situation, I would eventually reach a point where the floor tiles were being buried into the sand at about the middle of the island. I actually have 2 layers of floor tiles stacked on top of each other to make the ground floor area flat and level from front to back and side to side.
The rise at the back of the island is asymmetrical as well. The section at the back of the island, running left to right is fairly straight and level, but the 'arms' that extend forward are off. The left side ends very rapidly and the right side slopes downward (toward the front of the island) and reaches nearly halfway across the island.
Well, the whole thing has given me another idea. I want to build a 'sky temple' now. Perhaps if I raise the entire structure 10-15 feet off the ground and then start building, I might have that 'flat surface' I am craving to build on.

PS: That isn't a throne room, that's my home.

There are two doors on either side of the stairway, the left one leads to an upper floor where I have a dining room, a master bedroom and a guest room. The right entrance leads to empty space, with an exit at the very back, that leads out onto a small 'fortification' platform built around and under the tower at the back.
The very top of the structure is an open space where I have installed a handful of farming plots.
The area at the very front of the structure, between the main gate and the bridge, is where all my crafting stations are set up.
Most of my 'stuff' is still stored at my original hovel I built near the fisherman hut. I just can't be assed enough to go pick it all up and move it to my new 'summer home'.
