Click on the top layer in your palette; which should be the "Surface 2" layer. Now create a new layer.
Name this layer "EXTRA HUES".
Set this layer on -Overlay- mode, 40% opacity.
Activate SURFACE 2 layer and load it's transparency.
Now go back to the Extra Hues layer and fill the selection with a dark blue or dark purple. This colour should be very subtle and give our Dome just a hint of extra surface light.

(Feel free to try different colours to see how they effect the surface colour of the dome).

Alright then. For the most part, WE'RE DONE!
How does it look? Please don't worry if it's not exactly like the one at the top of this page. With a little practise and some further experimenting, you'll be creating versions of your own in no time.

This next part is completely optional and certainly not essential to achieving the general effect of the Dome.
But if you're feeling confident enough, by all means, proceed!
Ok, first make sure nothing is selected. Do that by hitting Ctrl+D.
(Which means 'D' as in 'Deselect')

1. Create a new layer and leave it on -Normal- mode.
   Pick the Air Brush tool and make sure your foreground colour is white.
   In the Photoshop default Brush Palette, about ½ way down, you should see 3 or 4 brushes that look like sparkles.
   Choose the sparkle brush that looks like it has a hole in the middle, with lots of points on it. Hold this brush over top of the brightest spot of the lens flare on the top left side of dome.
   Then move it just a bit up and left, but position it just inside the edge of the dome.
   Hold the mouse down for about a second or until you see the sparkle become a bright white.

   NOTE:  Be careful not to make the sparkle too bright or it will not blend with the surface of the dome. If it's too blunt looking just turn down the opacity level for the layer until the sparkle softens up a bit.
   

2. After you've made the first sparkle, go back to brush palette and choose the sparkle brush with no space in the middle, but also with lots of points like the first one you used.

   (Try looking just to the left of the first brush you used).

   Position the brush just below the point where the first sparkle was applied.
   Apply this brush so it's the same brightness as the first sparkle.
   If you don't get it the first time, just undo & try again.
   The brightest line of this brush should be slightly shorter than the brightest line of the first sparkle. They should both be pointing in.
   

3. Return to the brush palette.
   Pick the sparkle brush that looks like a big X (only 4 points to the brush).
   Position the brush just above the point where the first sparkle was applied.
   
4. Now this is where it gets tricky to explain.
   Go back to the brush palette and look for the last sparkle brush you haven't used.
   This brush should also be an X, but a much smaller one.
   We will use this brush to create a subtle glare effect along the top left edge of the dome, right over top of the Lens flare effect and the other sparkles.
   
5. Now have a look at the diagram.
   Examine the distance that each tip of the sparkle is from the center point outward.
   Position the tip of the bottom left line of the sparkle just above the tallest sparkle line you see and just inside the edge of the dome.
   Press the mouse down and apply the brush along the edge of the dome and over top of the other sparkles.
   Try to follow the arc of the dome.
   You want to move the brush fairly swiftly along the edge so it doesn't have a chance to build up in one spot.
   Stop the brush when you reach the edge of the brightest spot in your Lens flare effect. Or where-ever your eye tells you is good. This effect should also be very subtle, try not to overdue it.
   
6. Go back to SURFACE 1 layer & load it's layer transparency.
   Feather the selection by 2 pixels, invert the selection and delete.
   What this does is soften the edges of the dome, allowing the blackness that surrounds it to saturate it's edges.
   Thus making the dome blend in better with it's surroundings.

TIP:  Feathering an image's edges by 1 or 2 pixels can also be very useful
when trying to blend pictures together in a collage.

Pick the Cloning tool and put it's settings to:

• Normal / 100% / Cone (aligned)

Choose a fairly small brush. I used the 3^rd smallest brush in the palette with soft edges. Now hold the brush right over top of one of the dots and press your mouse button once. Do the same for the other 1 or 2 dots, but never mind about the really small ones. They're like freckles... they add character!

Voila! And there we have it.

Now there's just one more problem left to fix... our Glass Dome looks more like one of those plastic toy-bubbles that's been kicked around the block a few times!
It looks all dusty and scratched.

There is a way to fix this, but for the sake of personal developement I'm going to let you experiment for yourself to find the solution.
I know this may seem cruel, but you know what they say... "Nothing ventured, nothing gained!".

TIP:  if you'd like to remove the colour from your dome
just set the Surface 1 layer on Luminosity mode instead of Normal mode.
