I think I would like it more as "artistic" if it didn't have the shadow on the ground from the fill light. I see way too many shots with too-obvious fill flash, and as subtle as it may be, this is one as well. I think if you had shot it straight (no fill, even if it became a silhouette), or maybe just a little white card, it would have been more moody.
