I like the warmth created by the color shift. The patterns created by the branches and leaves also add interesting detail to the overall piece.
WHere this fails, imo, is the lack of a define subject - or main point of interest, if you will. The point near the light is obviously intended as such, and that's where the eye is initially drawn because of the high contrast there, but I can't define what the object is (the shape doesn't stand out sufficiently}, so we have a background with a highlight, but no discernable subject. Lacking that, it's kind of neat, but fails overall.
Just my opinion, of course.
