Picture Book | Material Tests pt. 1

Although I'm aware there's still a ways to go in terms of development with the story, I did some tests with materials so I could begin to think about how things could be aesthetically.
I hoped that this would either guide me towards a certain approach or 'feel' based on how the methods both looked and worked.

1) Layers of watercolour, repeatedly painted, lifted off with tissue, painted again

2) Paint both printed into with cling film, and applied to paper with it. Textural.

3) Block of paint, washed out appearance from being dabbed with tissue and lifted away with watery brushes. Has a greater sense of depth due to the multiple shades of the colour.

4) White pigment pen against solid colour. Too 'still' and lacks character, energy.

5) Smudged paint pens against varying levels of blue. Creates more 'movement' (important when depicting water!)

Collage. Ink applied on to large paper with tough-bristled brushes, cut out and assembled to form 'waves'. I quite like the appearance of this. When cut up the brush marks are sort of abstracted and look unusual, curved forms and multiple lines make good waves.

The method in which the waves are created is purely analog, and make a pleasant contrast against the very controlled line drawings of the boats. Would like to look at using collage even more. Contrast in materials and the tones they evoke also interests me.
