Here is Barbara's flower painting inspired by flowers from her garden. The shots she used as inspiration are below. I like her really interesting composition a lot. It's not easy to balance a painting where most of the main elements are on one third of the piece. I think that Barbara has done this really successfully.

If there were a few things I  might consider working on, it might be the following below as illustrated with a few quick Photoshoped notes below :

1. I might look to cut into some of these flower shapes to break up the big shapes of the flower clusters and within the cluster to give us some contrasting darker shapes which will pull the flowers forward. Also I try not to have too geometrical shapes for natural forms.
2. I would look at these red flower shapes and keep them a little cleaner, using darker shades of the red flowers from the color family to create volume rather than black.
3. look at the photo to see the cast shadows on some of the leaves. The shadow will typically be a little darker and cooler that the local color of the leaf/local object if the light is warm.
4. Look to push the darker shapes to set off the lighter leaves and flowers.
5. I'd think about increasing the chroma of the leaf colors in places. That is, a little less grey-green and a little brighter green. Not lighter but more color. I some cases here the  colors are more muted. I'd study when that occurs in relation to the brighter color,
6. I pushed the length this leaf to reach into this dark background space. I made it a little darker than the leaves in front of it. It serves as a value bridge to the darker background shapes.
7. I'd consider darkening the underside of these flower buds.
8. I might make the indicated shapes of the plants in the background a little cooler and brighter green. Having the warm yellows and reds back here take away form the strength from the red flowers a bit.
9. You might want to attach this to a stalk or branch off another leaf.

Despite several notes on Barbara's painting I think that this is really unique and interesting painting that will really sing with another painting session or two.
