I’d add deeper substrate, mine is filled halfway up with substrate which increases the bin’s width to 40cm and gives her more burrowing space. Burrowing boxes are okay for play cages but theyre not really ideal for the main cage since hamsters like to burrow across the whole width of their cage. If you do keep the burrowing box, it eould be better to move it off the platform incase she decided to jump off the top pf it, its quite a way down to the substrate and she could injure herself on that ladder. Otherwise, it looks like a good setup.
