Looks OK so far but could look better with a bit of tweaking

The faded look to the colours could be thought of as an "ancient" or "weathered" version of the sett. Maybe try a "modern" version with deeper, more vibrant shades of the same colours?

In terms of thread count, I think it would balance the design by taking the blue line one the outside of the darkest stripe and making it thicker. Sitting so close to another stripe of the same width makes it look a bit too static...
