Fruit is the first lesson for an online watercolor class, Sketching and Watercolor Journal Style, by Jane LaFazio. This is the first watercolor class I’ve taken as well as my first online class. (At least, no other online classes come to mind right now. I love taking classes, so I might be mis-remembering this detail.)
I like the colors best in the first one, but the pear is out of proportion. The pear size is better in the second one, but the lemon ended up a bit angular. The third one is pretty good, but I still like the colors in the first one best.

First effort. Pear too small.

Second effort. Lemon too angular.

Third effort.

The subjects. Jalapenos are a fruit, botanically speaking.
The lemon and pear are fake fruits; the jalapeno is real. As soon as I finished the third watercolor, I cut it up and added to a soup.
The first one looks yummier! IMHO, if you want exact proportions take a photo. Painting is about making the observer react.
I agree. It’s not supposed to look like a photograph; that’s what cameras are for!
