Four stars all around.
Obviously, nothing in this world is perfect, but this is damned near close.
To me, this object represents some sort of time machine, complete with its own marble-like universe set inside.
If god were real, he'd have one of these.
I am unsure of if the marble is free-moving (and thus spins) or if the cogs can churn with a little persuasion from the owner, but I feel as if they should. Spin the large cog, and it will spin the marble. At least, that is what I would've wanted.
Never the less, a very beautiful piece which draws back from the old days of pocket watches and opium. A little more design would have been nice, and a step towards AlchemyGothic's Spectrostatic Nocturnium sort of intricacies would be a step in the right direction. More intricate details, especially on the larger cogs, would have made this feel complete especially with the feel of the marble up there.
I forsee great things from you, don't let me or yourself down.
