it’s a nice size for them! They are going to enjoy it!
Just a couple of things though, i know you’ve said you’re going to add more things so my comments below may be things you’ve already considered:
I would put a couple of hay piles in the purple area as well as in the Midwest cage. Boys (which I’m assuming they are) need multiple of everything - so you will need another water bottle as well. The blue tray which is in the Midwest, assuming that’s a hay rack, isn’t big enough to be the only hay feeding area.
The black pigloo hidey - as what is presumably an enclosed, it isn’t advisable for two boys. Boys need tunnels or boxes with two exits. enclosed hideys means a piggy can get cornered and trapped inside it by the other piggy. Make sure you have lots of two exit hideys for them - youve got space to have several of them.
You will also need to find a way to cover the ramp from the cage into the purple area so they can walk on it.
The area where the ramp comes down with that grid directly in front of it - I’d put that grid back against the wall. As it stands, they can get to your wall and the wood skirting and they will chew it.
