Any computer graphics enthusiasts?

I don't know what would go with a red "X" - perhaps Teejaay may know?

Looks like BT doesn't like the funky url dropbox gave you with html spaces in it.  I made a tinyurl for you:

I saved it for you. 

Who?  Me?

Now to your original question.  I'm not very artistic, so take this with a grain of salt.

I would think any enhancement that would draw more attention to the brighter center spot.  Something like an oval fading from light at the outside edges to a darker center.

IMO the area of focus is too small. Too much of the picture is blurred too much. So either an affect to draw the eye toward what you want or a new pic with a bit more focus and maybe less around the edges. Hope that makes sense. Essentially the focus was too tight, I would like to see tighter focus on the silver clamps.

Yes much better.

A good photograph doesn't need explaining. There is too much going on in this image to guess what it's all about.
I'm guessing that it has something to do with micro circuit soldering of some sort?

For this to work the photo needs more depth of field, less extraneous (distracting) stuff, and more lighting emphasis on what part you want the viewer to pay attention to. 

Here is a quick edit to demonstrate cropping. However I feel re photographing would give better results.
