Well, here's a pic of my current base but it's not interesting at all - everything above-ground is mob trap.
I'm going to start building something out on the water soon.
Unfortunately I'm currently distracted by an absolute mammoth of a cave system I've tapped into right down near the bedrock
Also note the Nether gate. I've been through twice: the first time I quickly built a wall around it. The second time I realised I'd only built it on one side of the portal and was quickly killed when I appeared on the wrong side
