It's so mysterious! I got so many questions! What inspired you, where did the ideas come from?
EDIT: personally, it evokes me the idea of curiosity, exploration, and choice/specialization. You are in a desolate land, a marsh, that you need to escape somehow. There are many ladders leading probably above the dark clouds, that is, many opportunities, many possible trajectories to escape the marsh. But, choosing one makes you forego all the others. "Am I making the correct choice?", you'd ask yourself, getting your foot on the first bar of the ladder.
Besides, you don't really know what's above the clouds, could be good, or not. So, it is dangerous, chaotic, full of opportunities and a dive into the unknown.
Still, you gotta make a decision, and explore, because you can't just stay in the marsh.
That's what I feel looking at this.
