It is hard to use a panel, and hard to use anything with straight lines, in a OBW. However, I do think you're on the right track with yours, and it will come out just fine. I would probably move the blues with black in them to the bottom, and then decide whether to move the golds with black to the bottom. I think it might look like the "weight" of the quilt is sinking down, which could be very effective. Half the fun of a OBW is playing with the design! Be sure to post again when it's finished.
