A bouquet for a bridesmaid

My bouquets have been quite a process, it started with the thought I didn't want a "traditional" bouquet combined with my housemate in London and his vintage button collection.

I started by painting three polystyrene balls (the one for me is slightly bigger than the other two). The stems are made from an old wooden broom handle, sawed and sanded, and I've glued them into the base of the balls:

A lace bouquet holder was stripped back to the plastic base. I then covered the top with 'leaves' and the bottom with 'stems':

Many hours of cutting felt flowers produced this bounty:

Which then needed sewing together:

After some experimentation (with hidden pins), I chose to use my hot glue gun to attach the flowers to the ball:

I think the base still needs some leaves which overhang so my brain is running overtime. The flowers also seemed a bit flat to me so I added some wired pearls. What do you think?
