I can see the pictures, would you like me to add them to the forum for you so all can see?
Bubbles looks like a lil cutie. Good start to the bin cage. How deep is the substrate? Hamsters love burrowing so try making one end of the bin deeper than the other. If you want a cheap hide, reuse a jar (cleaned obviously) and partially submerge it in the substrate. You could put some of the substrate in or a bit of sand for digging and rolling around in. I'll see if I can find pics of my bin when my robo was in it to inspire you
