WIP 1
Based on my scenery thumb-nail sketches, I made a colour WIP (work in progress) on Photoshop to get an idea of the colours and positioning. After this I started to test different brush styles that I felt would work well for this image. I ended up settling on paintbrush-style Photoshop Brushes.
I used an angled brush from 'Calligraphy Brushes' to create the first WIP, as it was only to show what colours I will be using and to show the layouts of the different parts of the scene. I also used 'Wet Media Brushes' and 'RealisticPencilBrushes' for my second WIP (below).

I then used various paintbrush style Photoshop Bushes to add more detail to the colours on the ground and the trees. When I was happy with this colouring, I then worked on the metal in the trenches that are holding back the earth. I'm still not completely happy on how that turned out so if I decide to use this image in my finals, I will try different brush styles to make it more realistic.
