Definately red, Kelly. She looks severely sunburned in this one. Could be the light, or the film, like Jeroen said. There appears to be a shadow across both of their heads, too. I think there is too much wasted space in the frame around them, and my eye goes to the big hunk of wood in the center, instead of the people. The sunburn makes her teeth appear very white however, and her obviously colored hair shows the dark roots too much in this light. Perhaps more overcast sky would help that.
composition: too centered, could do with a tighter crop too. Light: slightly dark. Colours: oversaturated, tending to a reddish cast (what film did you use? Some films, especially consumer Agfa and Kodak are notorious for that).
Depth of field could be more shallow, leaving the background more blurred than it is now.
