From the computer picture, there does look to be enough contrast but in person, it might be subtle. It does look lovely from what I can see. The big question is: Do you like it ? Learn to follow your feelings about design, color, contrast. If you don't like it, then you don't like it. No problem, it's your quilt and you don't have to keep sewing it as it is. You change what you want to change, it's yours to play with. Good Luck with whatever you do !!
