>>6063880This is the same image, but with a shadow border much like OP. I wasn't entirely sure of how to recreate the effect, so I ended up using the Blend Tool in GIMP. I'm not so confident with this one, but I think the shadowed border makes it look better than just the plain background.
This one I could really use some input and advice on. I'd like to make the border look good, but this just seems subpar.
