I'd keep going. I'm actually working on my second one, and actually tweeked the pattern a bit by turning the center 4 patch 180 degrees. That produces a pattern where you can still see the original patch as a square. Wish I had a camera and knew how to work it to explain what I mean.
Again, I'd keep going.......really another one that I find myself going back to just to see what I can come up with using different settings, etc.
