Trying to Make a Transition!

I found it so hard making a smooth transition: I believe that it'll require a bit more practise to perfect. This is because I had to make layered frames where I would gradually change to opacity of the image until it became a new image. I decided to make this faded in transition rather than the straight cut as I felt that going from one scene to another like that felt very out of place, despite the fact that they relate. I shouldn't need any more transitions in my animation thank goodness but I still need to make it flow throughout.
