When I am learning a new FMQ pattern I practice it over and over on a small white board until I feel like I know how to move around the space and it becomes almost automatic. Spirals are tough because of the spacing to leave room on the way in to get out again. Paper (white board) practice will help you judge that.
Your spirals aren't bad and with practice will get better. Don't be too hard on yourself. The thread color here makes any irregularity show up a lot. With a thread that is closer to the fabric color these same spirals would make you happier. Just keep with it. And remember this is "hand made" and shouldn't look like a robot did it.
