I enlarged the focal panel quite a bit, but I did follow the sketch the rest of the way ;)
I started out with a 3.25-inch white circle, and stamped a little lawn fawn scene on it. I used the new frog from "critters ever after" and had him sit on the log from "critters in the forest." The bird and tulip are from "gnome sweet gnome" and the grass clumps, from "critters in the 'burbs." I did some simple copic-coloring and then masked all of the elements so that I could stamp the hero arts envelope pattern overtop in blue ink.
Since I was inspired by the retro sketch of the week, I'm also throwing this card into the current lawnscaping challenge - all about being inspired by fellow crafters.
