Big flower cards

I have had these large mulburry flowers for a while now ,thought they were a tad large,but they came up a treat layered up and glittered on the front of these rwo cards.
Both the backing papers have metallic finish so the glitter looks fine
I thought the cards were a bit bare ,I.ll see tomorrow if they need anything else,any comments welcome,Do you think they need any other adornment?
I would like to enter the yellow flower one in the following challenge
