Prepping for Christmas cards

Last year it was trees.  This year I am thinking I'm gonna do poinsettias.  I saw a little tutorial on this and thought I would give it a go myself.  Yes, these leaves are a little stylized.  The real ones are a bit fatter.  I might have to do a page of these where I do a bit fatter leaf, but I think these are gonna be what goes on the Christmas cards this year.

The two on the left have a yellow ochre behind them,  on the right azo yellow.  Not exactly sure the direction I'm gonna go.  Brighter, more in your face, or a bit more demure.    I'll decide after the next group of tests.
