Thumb Nailing on A3s 2

I asked my friend Josepth for advice on composition (he's an illustration student) since I struggle a lot with it. He gave me some good advice: Don't worry about the details. Make the thumb nails as simple as possible, you want to get your thumb nails to be seen and the compositions seen straight away. 
He also came up with an interesting idea of having a little  plant or seed growing in the last frame to communicate that the forest is destroyed but there is always the chance of regrowing ;communicates hope.
