Right now it's like an optical illusion, where the eye can't settle anywhere because of all of the incongruities in the current design -- e.g. the lines don't all line up, you're looking at it much closer than you normally would, and at a straight on angle, which would be unusual for a quilt pattern. Once you finish the quilt, have everything lined up and bordered, and have it lying on a bed, and are viewing from a proper distance and angle, you will likely still have a sense of movement from this lovely pattern and color choice, but it shouldn't give you disequilibrium! Really, you'll be fine.
