It looks good. You've got lots of room. If that's your only tank I would consider a quarantine tank, best option is another 220 and maybe a 75 or something. Depends on what kind of fish your into.
I see you have two big canister filters, they draw a ton of power. Keeping the hydro bills in check will be a point for yiu when talking to the misses.
I've been down that road, thankfully I won and have a bunch of tanks going. Goodluck
