Moleskine Doodles + Watercolors


I like to extrapolate/ morph/ extend one art project into another. These are creative experiments. Questions that go through my mind...

Can I do this on larger paper? Smaller paper?
Can I try this in acrylic instead of watercolor?
What if I started a page with a photograph?
What if I thinned the colors using a medium?
What if I added texture to the page before I added any paint?
I wonder what this [new] pen would look like on that paper?
Is it feasible to use this ink for a mandala?
