I didn't have time to iron my backdrop so I used a healing brush tool to smooth it out.
I added some sparks and darkened the top boarder of the photo by adding black and lowering the opacity.
I did my usual skin retouching and added shadows/highlights using a soft light layer.
I added an orange glow using an overlay layer. I only added orange to the lower parts of armor--anywhere that would be hit by light from the area the sparks were coming from (the lower left corner). And I added a yellow glow around the broach piece and stomach "armor" using the same technique.
