Cool idea. You see "painting with light" a lot in photography so the thing to do is make it different. Someone mentioned composing. The most important thing to always note is the "rule of thirds" pretend you are making a 6 square grid in ur frame. You don't want ur subject to be in the center of the photograph. Go find a spot that is different? How about a ranch? When I look at these photos and then see the ranch looking one you took I think of rounding up cattle, horses or pigs... I would say do a little shoot at a ranch. I'm not going to tell you what to do since ur the one taking the photos and going to be the creative edge in the end, I'm just giving you something that may help get ur creative mind flowing... Try lighting up things in the frame also, trees, fences anything really just to make the viewers eye move around the photograph. Good luck dude, hope this helps.
