That is a nice 3d structure, a \"natural\" street lamp - cool.
How about a longish filament with an over sized anther, it would be the anther that glows.
In case you don\'t know what those are,
click here for parts of a flower Or a cluster of anthers/filaments like in this
image of a tulip There are 6 anthers.
These would be like \"light bulbs\" the light source. The flower petals would be the light shade - imagine a red flower glowing red and shedding a reddish light around and upward, with your bio-luminance glow brighter and directly down. The translucence of the flower would be something like this one:
Back lit flower petals Note how where each petal over laps there is less light coming through.
If the player looks up when underneath there are bright points of light where each anther is.
