A skull floating through space(work in progress) with life on it. Traveling through the universe while the wheel of life spins.
It has huge potential. Maybe you can remove the grass and instead replace it with big roots which ends into the eyes of the skull.
Have you tried to give it some teeth?
And the material of the skull could be white with some little holes in the bone structure, because a real skull has a lot of imperfections and when it’s old the are broken parts.
