Here is a very quick card I made using stamps from the Winter Trees Stampendous clear stamp set. I have never tried airbrushing on glossy so I wanted to give it a try.
I began by creating a little scene on a piece of glossy, 4 x 5.25 inches. I stamped with Memento Tuxedo black ink. Once I got a layout I was happy with, I cut some Eclipse tape in an arc and airbrushed the hills with B02. I added a little B63 for some extra shading. Then I colored the deer with E33, the houses with B91 and the trees with G24. You have to be careful coloring on glossy with Copics, it tends to leave streaks. So I color quickly and lightly using a lot of the brush.
This little card took 10 minutes max to make. Finished size is 4.25 x 5.5 inches.
