Grapefruit painted

This wasn’t a great success. I tried to go back and darken the shadows and only ended up messing the paint. It’s my first try using watercolour paper and it’s a bit different to print paper. In print paper the colour gets absorbed and doesn’t come away when you go over it again. In watercolour paper the paint wipes off if it’s still wet. I need to learn more about applying washes, especially to show difference in tone.
