Photo Update!
I believe the height is alright for the main structures and have started to fill in the spaces where the figures will be. I have focused more on the approximate height of bodies than the actual features so far to make sure it all looks proportional.
I have also discovered that I will have to fill in a lot of the empty space that is shown in the images of the panel in order to make sure that the casting process works well. For example: the area behind the little bridge wall will have to be solid to avoid any issues with the making of the silicone mould.
