This is a REVISED verion. Redone.
I'm quite happy with how this turned out. I spent the longest time on the clouds and I still think they could be better. It looks much better too now that the unicorn has more character since the older version.
And cross-post from the old version:
"As I follow the great star to the land of my kin, I cherish this last sunset."
A unicorn, in the last of her days, travels to the lands where her kind pass their life back to Gaia.
The reason for the unicorn not to have a reflection is, that a reflection is like a memory. Since the unicorn is dying, so to say, there is no reflection because that would leave a sad memory for the land around the river.
