Awesome illustration and detail on the boat's reflection on the water if you were familiar with anamorphic flare lens,you would've used it to set detail on the lamp for lighting,but whatever,awesome job
Only one suggestion: The floating object could use a little more work. If it's a shoe, as the shadow sugests, it would ride lower in the water due to its weight. If it's a bottle (the only thing I can thinks of that would ride this high)m the shadow's wrong and I'd suggest giving it a neck for clarity. And if it's SUPPOSED to be unclear, I'd blob it and fuzz the sadow a little (which might be a good idea anyway because of the water ripple).
