My manzanita branches Centerpieces!

Hey! So I wanted some help! Let me know what you think of my centerpieces and what I could add to it to make it better (if anything!) BTW for my real centerpieces instead of the flowers at the bottom on the pot, i'm going to use blue beads. I'm also going to put 3 or 4 blue tealight candle holder (votive) with white candles inside them around the table.

I bought my manzanita branches at Blooms and Branches, which turned out great!
I also bought my flowers with pearls inside them at Michaels. Everything probably came out (roughly) to $18.

I spray painted the branches a glossy brown.
The white vase I bought from Christmas Tree Shop for $1.
I also had to buy Plaster of paris. I got mine at Michaels for a trial, but you can buy a 25lb one at Amazon for about $25 and that should be good for all of your centerpieces.

(The only thing missing in my calculations is the white rocks I'm going to put, instead of the flowers...but that shouldn't be too much)







--update--
I put in rocks instead from IKEA...they were about $2 for a pack, i bought way more packs than I needed!
Real total was around $20 each centerpiece :)
