Step 1 - OK I probably didn't need to show you this - the blank page. I've started using watercolour blocks instead of pads or loose sheets, and they're great! You dont' have to tape them down at all.

Step 2: Using masking fluid, I masked off the edge of the paper and created three separate panels.

Step 3 - Colour washes for the background. Here I've done the first two. I tried to give a feeling of the day passing - using the colours of sunrise, midday and twilight.

Step 4: As I wanted to convey the idea of the same tree and bird changing over time, I wanted my tree to look the same in each panel. I usually paint my trees freeform, without sketching them first. This time, I sketched a tree in pencil first, and transferred it to the 3 panels so each would be the same.
