After some food feedback I finally edited through my second idea to make it more understandable. Feedback would still be appreciated on the structure and the length of the story, but I have changed some of the conflict and tried to make the story more consistent in some ways. 

After some feedback I decided to re-write my initial story, taking on the feedback I have been given while also making some choices. Firstly, rather I thought rather than the conflict being between two guards, it could be between a guard and a prisoner who's running the prison, making the external conflict more extended than just the guard wanting to fit in.  But, I don't think the story is quite there yet and feedback would be appreciated. For a start I don't know if the guard / prisoner conflict works in relation to the method he takes to pursue becoming a bodybuilder (like is the conflict too dramatic to justify what he does or is it too un-realistic ?) . Also I still have some problems with my ending, as I was torn between having this ending, that I'm worried could be seen as a cheap ending, because the first scene plays out with a clear goal, and it never gets resolved in the end, or whether I should, of have had a happy ending, where the guards hard wo...

After a conversation and some more thought I have finally managed to narrow down the mind maps into two story ideas that I think I can work with. I'm happy that I managed to draw away from the setting being in a prison that I felt made the idea feel generic and easy, whereas with these ideas I feel I can manipulate the layout or the tone to see how it effects the final piece, although I still have a way to go with characters, conflict, story layout and ending. Feedback is still appreciated.

I took on board some feedback from my last mind map and tried to broaden out with some more ideas to see how the story could go, I'm still not certain how the story will go, but I have a couple that i could develop, but feedback would appreciated so I could get an idea of what ideas work.

 I had the most fun planning this, but I did have some trouble deciding what to do with the microscope and I feel I would like a few more suggestions however I already have some ideas formed from doing this and feel confident enough to plan out a plot and story from using these. The prison I feel is the most flexible feature and the one I might mess with more in the story because it could be used metaphorically rather than the microscope which I feel some people might not know what it looks like. The bodybuilder I might play it safe and make it male so it fits the archetype better but play with what visually is a bodybuilder within the story to make it more interesting.
