Mr Kool...you've got shots that could work but your shots are over-contrasted and slightly underexposed.
maybe:
pict #2 should be good if you could zoom in into the fire, like a macro shot...but be careful, do not use digital zoom...only optical zoom. digital zoom equals bad image quality.
pict #3: give more space for the sky.
pict #4: try to get more angle on the campfire...i think, a shot fr the top might work, plus a phony model to add to the drama.
