Rapunzel Tower Moc

First time doing a moc like this. I used Stud.io to design. I also took a lot of inspiration from other MOCs out there however none of them have instructions available so pretty much designed entire inside. There are a couple of stability problems that I need to redesign to fix. Im not sure if the actual top is a big too oversized for the tower. The roof is designed to come off as well. I made this for my girlfriend as she loves the movie Tangled. Any thoughts, ways I can improve? Thanks! ...
