One of the basic requirements of a good watercolor is mastery over the washes. And that comes by practice and practice and practice. So, anything you feel like painting, just go ahead. I came across this watermelon which appeared juicy on that reference picture and just wanted to paint it, though I know

it's not as juicy as the original is. I am somewhat happy with the overall result. But the washes... I know it's a long way to go for me.
