The centre block and the middle left block are grabbing too much attention. The rest of the quilt is quite balanced. When I look as the middle left block, all I see is a spool block which doesn't really gel with the rest of the quilt. As the blocks are all the same, I know it has to be the colour, so I would try shuffling a few blocks to create a better balance. The colours are great and it should be a wonderful quilt.
