I've made a few adjustments from the last composition, building on what I had already laid out (though I will have to re-paint a new base as the current version's layers are an organisational mess). The mountains in the distance are a little more easy on the eyes whilst still maintaining the graphic shapes. Currently they are suggested to be covered in pines, a type of tree that I enjoy to paint yet isn't what's common in the area I'm setting this scene in. I would like to incorporate more of the cliffs and biodiversity in flora of the Périgord Noir area.
As the scene is taking place in either late dusk or early dawn, the colour palette becomes limited to being influenced greatly by the sky colour and any artificial lights in the scene. I'm trying to stay true to this whilst also finding ways to bring in the suggestion of other colours, especially in the hives as currently they are quite cold and grey.
Between the foreground and the background, I've added a little more space to create breathing room. I'm walking the fine line between keeping it simple/readable and having enough content to effectively communicate the idea. 

Via a few little field trips around the area I asked some local bee keepers about the design of the hives and learned a lot about why the small stuctures look the way they do. There often needs to be a lower set entrance with a ramped floor to stop water from collecting and small staggered roofing to protect from the rain. I sketched out a few hive designs based on what I saw and heard, keeping the key features of artificial hive design in mind. I could go crazy with wacky out there scifi concepts but 1. I need to make sure that the audience can visually identify that they are bee hives without reading the description and 2. my personal taste lies more in hard-scifi with a hint of magical realism. 
An extra treat from my research was finding out bee hotels exist and are also adorable. Hives are for honey bees that live in a collective. The other genus' of bees are actually solitary and only require a small space soley for themselves. They still collect pollen and are an important part of the ecosystem. Clealy I must make a space for them in my sustainable world. Bee hotels can be varied in design and allow for a little more flare. I've placed a rough design in the scene and I like the base for what's there.

The Town in the background has been changed to reflect the local area more, incorporating small pockets of housing and commercial lanes winding along the verticality of the landscape. 
In the foreground I've added more lavender with the hope of being able to showcase the visual medley of aesthetics the plant can provide.

I was struggling with trying to accuratly layout the mushroom-like antenna so I jumped into blender and quickly modeled the main design and placed it into perpective. Turns out this saves a lot of time! The next phase is creating the iterations I need for the antenna design. I enjoy the current simple silhouette but know deep down that I haven't explored the potential possibilities.
