Mixed Media collage (WIP)

I haven't decided what to do yet with this, but I am liking how it is going so far. This was an aluminum sign from the dollar store. Amazing what some paint, compound and powders can do, huh?

This is about 6X6. I used white caulking as the base on the metal. I added texture to it to give it some depth. Then I did a paint wash of blue green and black, starting from opposite corners. Dried it with the heat gun, then used pigment powders over it and sealed it with gel medium.
