Needs more of a focal point. The blue flowers in foreground are nice, but the dominant shapes in the photo are the tree trunks, and they're not very interesting.
Its hard to see any clear shapes here, its to complex. You went to far on the saturation too, its shows on the blue flowers and red/yellow background sky. In another challenge and without the oversaturation it would do alot better.
Don't see connection with shapes theme. While the flowers make an interesting subject, the blue is oversaturated, as evidenced by the blue on the trunk of the tree and in many of the leaves.
Very strange colors. The bark is purple, which might be a problem with fringing that occurs when you try to compensate for bad exposure. also, the sky has unnatural colors. Sorry, but the image really needs some work.
