Painting a Rock for a Children's Picture Book

I’m painting a scene where my characters are walking among huge boulders. I spent an hour trying to paint this rock. But there’s something missing — context. It needs some characters walking past it to give it scale. Standing on its own, it reminds me of a piece of pie. Some areas at the bottom that look okay, but the top looks too smooth. It needs sharp edges where the rock’s facets turn from light to dark.

When I run into a newbie problem like this I eventually remind myself that I’m a rookie at painting and that I’m on the right path. I’m stubborn and curious — I know I’ll get it right if I soldier on. That’s what art soldiers do.
