You look like a very ancient sol divinity so pretty much anything ? you can change form, float or teleport, turn people into whatever you want, create light , illusions ....

You can drain the colour of everything around you and fill it back in at will.

You can play hypnotic harp music, it sends anyone that hears it into a trance and they will then follow you anywhere.

you put people to sleep and haunts their dreams

You have power of shadows; you can merge with any shadow and emerge from any point touching any other shadow that touches the one you went into.
You can animate and detach your shadow while your body sleeps, travelling about as a patch of shade defying the normal laws of physics and light.
You can manipulate the shadows that are created by you or fall upon you; from making it seem as though an invisible light source is changing the angle of your personal shadows to full on shadow-puppet plays from holding up a single hand against the light...
When you don't concentrate, shadow spills and pools around you like a visible scent wafting from a perfume bottle...

I need a drawing pad, it's hard to describe this.
But Neith, I promise you it's an awesome power!

You can shoot fireworks out of your hands

Your radiance is capable of healing people and bringing them back from the very brink of death.

You have a sonic scream that destroys anything in front of you.

You can fly, but only under moonlight.

You can sing anyuthing perfectly
