Create a new image, 400x200 px.

Create a new layer. (this can be done by hitting CTRL+Shift+N.)

Set your foreground color as black.

Shift+Backspace, and hit OK. (This is the same as going Edit>Fill.)

Create a new layer.

Right-click on the new layer and select Layer Properties. Name it "Center".

Hit "J" on the keyboard to put on the airbrush tool.

Mode: Normal

Pressure: 82%

Select this brush:

Make white your foreground color.

Draw something like this:

Click on the layer that you colored in black. (It should be automatically named Layer 1.)

Create a new layer.

Select this brush:

Make your foreground color #B9F9F5 (or something close. Just a reaaaaaaaaaallly light cyan.)

Now, I highly suggest zooming in a tad and expanding the size of your picture. You can zoom in with the Navigator platte on the upper-left hand corner of the screen, (in the little percentage box type in 332 and hit enter,) and then put your mouse on the lower right-hand corner of your picture so that you see the dragging cursor, then click and drag it so it broadens your working area. I would make it fill your whole screen. It will make life easier.

Now, on this new layer, trace over the white line. Be sure to scroll left and right in order to view the whole image.

Once again, click on the black layer and do CTRL+shift+N.

This time, select the brush on the right side of the last one you selected. (under the brush shape is '21'.)

Forground color= #F5F9B9.

Do the same tracing technique, except this time trace just a bit above the bolt, and then do it again on the lower of the bolt.

Go back to the black layer, and create yet another layer. You'll get really used to this once we're done with this tutorial... but since we're going to do it so much, I'll just call it the New Bolt Outline technique.

Select the brush with the '27' under it.

Foreground color: #F9F091

Trace over the bolt again, on the upper and lower, as you did last time. We'll also get used to this, so we'll call it the Tracing Technique. (TT).

New Bolt Outline.

Select the brush with the '35' under it.

Foreground color= #FFDD67.

TT.

Now it should look something like this:

If you find Layer 2 (the first trace, the one with the light cyan on it,) you can always click on that layer, then next to Opacity: you can set it to whatever you want. I put it on 74% for this result:

Hee hee had to do that... Anyways, now it needs little zappies. How do you make zappies? Well, click on the Center layer and create a new layer.

Select the paintbrush tool and then this brush:

Make white your foreground color.

Now, zoom in REALLLLY close, so that all you see is just bolt, like this:

Next, starting from the inside of the white bulb (the one on the Center layer,) make little zappies, like this:

Do those for the length of the entire bolt. Try not to let them go into the black background, though... just retain them within the yellowness of the bolt.

Next, click on the black background layer we created.

Select a dark foreground color other than black. Reds, blues, and greens seem to work well, but you can use anything you like.

Select black as your background color.

Filter>Render>Difference Clouds.

You can either leave it where it is right now or hit CTRL+F (repeat last filter) a few times to make it nice and mixed up.

Now, select another dark background color, and set it as your foreground color.

Hit CTRL+F.

Filter>Render>Lens Flare...

On the little preview box, click on a place where you think it would go well on. I personally try to get it to look like it's on the bolt. It may take a few tries. If you mess up, hit CTRL+Z to undo your last move. I used the 50-300mm Zoom lenns with 100% brightness.
