Responses to first edit

In response to my first edit of my video responding to my Mum's memories, I have made a list of things i should experiment with to improve the final video. These adjustments are a process of trail and error i suppose, trying out various changes then reviewing the video again and again to see which changes i should keep, or loose, depending on their positive or negative impact on the short films. The adjustments I am thinking about making after reviewing my first edit are: Colour instead of black and white, would the use of colour enhance the short film's emotional impact on the audience or does black and white symbolise the sadness of the subject, and create a more powerful, hard hitting experience? Repetition of the video clip in slow motion rather then a still image throughout, would the audience feel like more was being revealed about the person if the slow motion clip was repeated throughout all of the voice over, rather than one continuous still image. Or does the black and white image give the audience time to really study the person who's memories they are listening to, which would have a more powerful impact on the audience, also which would help capture the audiences attention for longer? Positioning/timing of background music, could I position the background music differently so i could avoid the slight repeat at the end of the video to ensure that it fits to the time of the voice over? Would this create a more professional finish to the outcome? Is the music choice correct? Is there another music option that would suit the video better, possibly one that is the same length as the voice overs, or without any lyrics as to not distract the audience from the narrative of the video, or maybe combining two or more pieces of music to make the video more interesting?
