06 To add glowing lights use a brush to draw lines freehand at 100% opacity. To twist them, use the Warp tool: Ctrl/right-click on the layer with the Marquee tool, twice. Paint each line on a separate layer before merging them all together. Then duplicate that layer, add some Gaussian blur (Filters>Blur>Gaussian Blur) and lower it to 30% opacity before merging them again. Here I like to rotate the layer to find a good spot for the lines to be placed. You can also twist them all together now with the Warp tool to give them a bit of motion. Some radial blur on this layer might create a nice effect too.
07 Now select the layer with the stone textures from step five. Copy these objects and place them on another layer on top. Make them smaller and maybe change the shape of each of them just to get a bit of variety in your asteroids. Multiply the layers and move and change the new ones so they look different from the first. This way we create a kind of meteor belt with a lot of smaller stones in the background. Add the Overlay Layer effect to that layer and the objects will blend well into the backdrop, and look different to the larger meteors in the foreground.
08 Some glow will draw the eye to the focal point, so let’s add more light to this part of the image. Create a new layer and paint inside this area with a bigger brush at 50% opacity. Then use Gaussian blur (Filters>Blur>Gaussian Blur) again before repeating this step a few times until you are satisfied. Work within the marked area and try not to overdo it.
09 Choose two areas where you want to create a warp. Add a new layer and mark out the areas, filling them with a colour just so that they are more visible in the layer view. Hide this layer and take a screen grab of the actual image of how it looks right now, and then create a new layer pasting in your screen grab above the mask layer. Show the mask layer again, then Ctrl/right-click on the screen grab and select Create Clipping Mask. You’ll see an arrow appear on that layer, assigned to the mask layer. So whatever effect we decide to apply to the captured image, it will only be visible in the areas of the coloured shapes.
10 Now use the layer effect Liquify (Filters>Liquify). This filter has an interface enabling you to see the full image. Decide on the size of the brush and choose the Twirl Clockwise tool. Be careful to not smear it too much, but do explore the filter and brush sizes. This, combined with the Pucker tool and a smaller brush, creates similar effects to the implosion seen here. And the mask is covering up the edges of the effect perfectly.
