Really pretty fabric choices!
If it were up to me, I would look for a fabric to go between 8 & 5 as has already been mentioned and also one to put between 4 & 7 as that is a big jump in brightness.
In addition I would consider replacing #6 as on my screen anyway it seems to be a different blue from the rest (more hinting at aqua).
Can't wait to see how this comes out! I know it will be lovely.
