Experimenting - need to push more?

I am continuing my exploration of the Beara landscape through accordion sketchbooks in watercolour, colour pencil and Neocolors. Working from photos I took the last time I was on the peninsula. I'm thinking I need to push the mixed media element more. But at the same time, these make me happy. Maybe I don't need to add layers and layers of ink and gouache?

Here are some more of the colour swatches I did before painting. (See earlier post for more)

And a few shots of how they look as an accordion sketchbook. (I can never take a good photo or video of these, as skill I need to work on!)
