Cool idea.
A more close up and the light centered underneath the battery would look better IMHO.
Maybe you can still retake the shot?

but if the light was centered underneath the battery, it probably won't look like it is floating then.

I agree with k5683, the light placed where it is makes it look the like battery is floating which adds to the effect a lot.

On another note, the high res makes the shot look better when you can see the close up apposed to the standard picture and an even higher res would look totally awesome. Either way I think this is an excellent shot and nice creative thinking.

Thx for your nice comments

Wonderful action and expression.

I really like the result, good luck to you

is selective coloring allowed now?

It's not selective coloring, he used tools and techniques that are allowed...

As Mikaelbg said Ade this is allowed you can check out this sbs to see how it is done.

Adjusting the color channels acts on the picture as a whole and therefore is not selective. Now if only the cab was in color and not the windows and signs ect. then it would be selective.

ok, had to ask.....there was no sbs, and so I wasn't sure.

Nice work

Great effect!!! Love it

That shot is very good in Orange/Black
