What is in this image? Be very specific. Scientific, Engineering style! No emotions, no opinions, no metaphors. Just the facts, as detailed as possible.

The image depicts a line drawing of two gnome-like characters engaged in an activity involving a large cut-down tree log. Both characters are wearing hats and are positioned close to each other with a toolbox beside them. One character, on the left, is holding a magnifying glass examining the severed surface of the tree, which suggests a detailed observation or analysis task. The character on the right points at the tree, which could indicate a discussion or explanation about the object of their focus. There are background elements including bushes and a pattern that suggests a brick wall, as well as a diagonal grid pattern overlaying the entire scene which could be interpreted as a guide for coloring or further detailing by the viewer.
