Experimenting with Collage: "Rules"

• Selecting the best combination of forms through thumb-nailing, I have been making a series of collages derived out of my written manifesto on compositional balance, as according to Arnheim. 
• I am finding it sometimes hard to apply Arnheim's theories to the making of my images. It takes a lot of thought to generate a collection of forms that both look visually appealing and in some way apply to these rules. 
• I think in many aspects my own creative intuition does play a part in the making of these images. 
• So far, within the collages, I have been experimenting with my combination of media - using gouache, mono-printed textures, coloured card and coloured pencil.
• The coloured card, in itself, is good to use physically as it allows me to move elements around and therefore play with layout - but the texture of it doesn't give a very nice finish. 
• I started using gouache and coloured pencil together - but felt that it not provide enough differentiation, so have resolved on using the mono-printed textures and gouache paint.
