Artist's Painting

Open wide, take a look.
I'm a fairly open book.
Naught to hide, plain to see.
Shroud in clouds of mystery.
I'm a mess, I confess.
Peer inside and try to guess.
What goes on, in my mind?
Don't be scared of what you'll find.
In my world, in my head,
No words spoken. Nothing said.
Come on close, take a whisk,
Be aware of what's the risk.
Swirls of paint, spots of white,
It's my spell in orbs of light.
Take a look, at my wand,
Just a paintbrush in my hand.
