What do you think about theses centerpieces? Purple Tulips, Lav roses, and mauve calla lilies??

1st pic is my inspiration of putting it together.

2nd pic is of a vase that is similar to the vases i'm using but mine are bigger. And I'm making a fabric belly band around the vases.

3rd pic is purple tulips from Sams club. 100 stems for 101.28 shipping incl

4th pic is of the lavender flowers i'm mixing in with the tulip again at sams 125 stems for 83.68

5th pic is of the calla lilies I'm primarly using for the BM and bouts, but I will have some left over to throw in the centerpieces. 150 stems for 162.76

Does this look good together?? Do you think someone with Very little flower experience can put this together a couple days before a wedding??
