The sand colour represents the sandman and the eyes are like his too-
There is a creature that comes to you in that space of time just before you fall asleep. Some time after your eyes close for the last time that night, and some time before you fall into a state of unconsciousness, he materialises over you. Is he an angel or a devil? No one is sure because no one has ever got a good look at him. Some claim he has a head shaped like the crescent moon, and dark eyes with stars inside them. He carries with him a bag of magic sand, and he sprinkles a very small amount over your face. Some say it twinkles in the moonlight, like a thousand tiny stars just over your face as they fall. Some say the sand actually sounds like a music box, or the flitter of faerie wings. No one has ever really heard the sound however, for by the time the sand touches your face and alights about your eyelids, you're on your way to dreaming.
The grit or 'sleep' (rheum) in one's eyes upon waking is supposed to be the result of the Sandman's work the previous evening.

The swirls on the hind leg are based off the front cover of the "Wonders of the Universe" book by Brian Cox and Andrew Cohen
Dream catcher to catch dreams around neck
On his/her back there is the Aries constellation which I believe is yours
And on one of the hind legs is what is supposed to be a nebula :)
Oh, and the light vs dark thingy
