Pencil Drawing of Artificial Christmas Flowers

I bought these flowers at Christmas because I thought they were lovely and festive.  They have been sprayed in rich gold and there are some bright red wheat looking flowers in there too (sorry, don't know what they're called. No green fingers here).  It is a really nice arrangement that I would like to paint one day so that I really show the colours.  The vase is a really vivid red black and grey too.
