I think it looks good ... the one thing I did with my quilt was take a step back and squint at it to see what jumped out at me too much (kinda like squinting at christmas tree lights to make them blury if you know what I mean?) ... I did it in the pic you posted and as others suggested - the light/bright blue is doing that for me. Again - the coloring may be off ... but maybe stick to smaller squares with that blue if you're in love with it?
Hope it helps!
