I think it's not too bad, but the colors are very pure. May be a good effect (think of Japanese indigo quilts), but could be also a little bit boring. So my second try will be to look for more nuances. In the picture I saw greens and browns too.
This wider range looks livelier.
Well, I like this one better, but best I like to add a very little pinch of exotic spice, means a contrasting color like a warm red in these cool blues.
That will do.
