Wow, that's a lot of panels! However, I think they are well organized/structured
I only have one suggestion: I generally think the [Back] button on some of the sub-screens are hard to see. You could make it bigger, but a better idea might to put the sub-screens into a popup window! E.g. when you click on Ellie, instead of changing your screen, you could popup here information while the tabbed panel underneath is still there. I might make more sense as you can still see the active tab but also the popup window in the center to edit the current selection.
