For "turning out not as well as you hoped" this turned out amazing! The lava is well lit, the foreground is dark but still good looking, and the sky has a decent lighting. All in all this is a great shot!
I think you misunderstood the caption. This photo was actually taken by Iyan, the person who took us there in a boat. Unfortunately, my night photos didn't turn out (though the day photos turned out great).
