Light Painting titled "Incomplete"

I haven't quite achieved the effect I was looking for, but work has moved in, the holidays have moved on, and night shoots have been buried for the time being.  I was trying to get a nice clean shot of the truck exterior while also capturing what's under the hood, along with some fancy-shmancy light painting.  Obviously I have some work to do, but feel like there is a good start buried in these captures.  These are all single exposures completed under the cloak of darkness with various battery powered lights from around the house (flashlight, fluorescent lantern, laser pointer).

The basic process is simple but a bit tedious and reiterative (i.e. do your light dance, capture the shot, wait to see if it turned out).  I start with the use of a remote to open the shutter using the camera's bulb mode (camera must be stable, I used a tripod).  Then with shutter open, starting with the hood up, I light a portion of the engine, and then finish the effect with the hood closed.  If you look close you can begin to see the effect I was going for (inside and outside the hood), but I need a bit more time and some different light to make it really work (I think a nice flash with a colored gel would work well).  Perhaps I'll get another chance the next time I clean the truck...next year!  PS - If you look close you can see some lighting smears, thats me hopping around with a light source and a piece of card board box trying to get the light to the intended spot.
