I asked my teacher: did I paint the watermelon incorrectly?

He answered: nothing was wrong with your watermelon, only you did not cut it right, that was all.  😓

Do I have to learn how to cut watermelon before I paint it?  I know, I know I failed that perspective drawing class while I was in high school (Now you all know why haha…).

*I was told: slice the watermelon on the darker green lines (stripes),  seeds will be exposed and make it easier for us to remove them.
