My point of view:
4 - oversaturated and overshraped.
5 - well done, looks good on the eye (even thou its oversaturated)
6 - also well done, it is blurred, but overall effect is good
7 - different than the others, and thats what I like. also excellent bluring/sharping. best work here
8 - colors are good, but its oversharped. it would be a whole another story if it hadnt been oversharped
9 - different, but waaay too different

yellow and pink just dont match...
2 pt - 7
1 pt - 5 or 6 i cant decide... lets go with 5
