Thanks for the comments everyone, this was my first submission ever. I'm a total beginner with photography but i've been reading up a whole lot. Guess it's mostly experience from now on :)
I quite like the disembodied nature of the shot. I wonder if it would have looked even more striking if you'd cropped the top and bottom of the lamp so that you're left with just the lava with black either side?
My favorite lava lamp shot in this challenge. The green is really great, love it bright like that. I like how you place the lamp to the right side of the photo leaving negative space.
