Flower Bouquet - repeat of smaller painting

As I have been doing some paintings, I've been redoing the same subjects.  So I'm painting flowers multiple times.  I recently painted these for a 5x7, and in a more blue tone.

It's really good practice to explore a subject more than once, and use better colors.  I'm pleased with this exercise.  Some parts of it are great, (vase, blue flowers, table)! Some of the actual flowers could use improvement, but there was no point in continually reworking them.  Time to finish it and move on.

Notice the flowers have a much brighter because I glazed some red over them in the next picture.

I totally struggled with the middle yellow flower.  So tough!  I redid it like ten times.
