Brush Mask

There are 3 slight indent lines around the center glow in the chest of the Iron man suit. These are very vibrant, so to bring them back to being more blue and appearing indented I'll be using the brush tool which lets me paint the mask over more of the layer or remove the mask, it works similarly to how the eraser tool works, having brush size and opacity.

The way the Brush Tool knows if I'm adding mask or removing is based on if I have black or white selected, int between gradients can be selected to intermediate effects.

I had a fairly large brush size size set of 90, and the opacity set to 25% as I didn't want to completely remove the mask resulting in an abrupt change when it is a glow effect. The overall glow I feel is too strong so the large brush helps remove a lot of the mark.
I also changed the brush to 100% opacity and a smaller brush and removed the mask completely from areas where it shouldn't be, such as areas on his stomach area where the glow wouldn't reach as well as his neck, left arm and legs.

This is the chest before:

This is the chest re-done:

I also tweaked the HAL Red circle a bit, angling it better for Iron Man's position, and having the dark ring showing making the glow stand out more. I was going to do the same with the palm one, but the full redness of it makes it look like a smaller more intense light in the palm of someones hand.
