Planning of my movie poster

I have been editing this picture on adobe photoshop to use on the movie poster of my teaser trailer, so far I have edited the picture by making it darker, i believe this will get across the horror convention of my teaser trailer. I'm hoping that this paired with the stance and costume of the main character will really put across the spoof horror theme.
What i plan to do further with this poster is to add the title INSIDEOFRUS at the bottom of the poster, above the title i will plan to put in smaller writing , 'from the makers of......' and make up some previous movie names as i see this as being a popular convention of movie poster.
Considering how this looks once i've added these i may include some quotes such as 'Best spoof horror of the decade -The Times' to really make it portray a movie poster and really get across to the audience the genre of the film.
Also i believe that using conventions such at this would really pull the audiences attention into my movie poster.
