Film Poster Deconstruction II

I've chosen this poster to deconstruct because it uses one thing I can relate to in  my work, and one thing I can use for my own knowledge. Firstly it uses a train which is a vital part of my film. Here the train is portrayed as being pure evil. This is done with lighting because the train looks like it is emerging from hell, a hell it has created. This effect comes from the dark night sky, and more prominently the plumes of grey smoke coming from the train. The poster on the left looks an awful lot darker in color and tone than the right which is quite mysterious, especially because of the glowing box. Could this  be the hope and saviour of the story, or could it be powering the evil looking train? You can't tell an awful lot from these posters which is one of the things that I like about them. It just leaves you wanting to know what on earth is going on. The poster has conventions that I would like to use in my poster. One of which is a title. In both posters the titles are clear, and even with the dark and cloudy background they stand out enough to be seen from across a busy cinema lobby. Another thing i'd use in my poster would be the location of the film and the main and featuring object. Just as in my film, the train in this poster seems to be the main feature. The train in my film will be slightly less... evil this this on appears to be, also at this time my idea for the title of the film is simply 'Metro'. Consequently I would like a picture of the metro logo on a metro carriage to be the actual picture that the poster is based around. However just as much as I like these ideas, there are also some aspects of these posters that I am definitely not going to use. One of which is the dark colour pallet which has been used throughout the posters. The metro logo is yellow with black font. Kind of like a Bumble Bee, which are recognized as quite colourful creatures. If any background is able to be seen on the picture I would like it to be a clear blue sky, I want the film to be cheerful and funny if I can achieve it, so I need the poster to reflect this.
