Yeah, it looks like or tunnel, or vortex at any rate. A whirlwind of Irises on a dark night, illuminated by a flashlight. That sensation is heightened by the asymmetry. Very nice work and thanks for allowing us to see it.
He who dwells in the shelter of the Most High will rest in the shadow of the almighty. I will say of the Lord, "He is my refuge and my fortress, my God in whom i trust". Psalm 91: 1 and 2
