'Daylight to Night' Brief!

My current project I am working on is to create 3 large canvasses based on an surreal exploration which my client wishes to hang on the wall in her home. It is important I do lots of research and experimental work for me to achieve the best of my abilities for my clients tastes.
The theme I am working on is daylight transforming into night, which may sound easy in itself but is not as I am blending different features to one another to create in a way, 'like an illusion'.
I will be painting all my compositions onto the canvases.

I will start by researching features that have been discussed such as autumn leaves dropping and floating in the sky which then turn into beautiful butterflies as they fly higher into the sky then turn into twinkling stars.

So here are a few images I have been looking at;

Exploring the different shapes and sizes of the leaves

Stars

I will now from researching these features, create some of my own compositions which I will show later on, with my own ideas and reflection.
