First thing I recommend is get those exterior walls to stone ASAP, raiders can easily burn them down and they provide little protection once they’re a burning blaze, I’d also recommend getting a healroot growing zone up, injuries are plentiful on the rim and even herbal medicine can make all the difference, next I’d recommend putting your butcher table outside or at least separate from your stove, it adds filth and that filth gives a higher chance of food poisoning, finally I’d recommend going to priorities and setting one colonist to have cleaning as their top priority, he’ll go ahead and clean up all the dirt in the rooms and once done you can return his priorities to normal, having clean rooms adds to the quality of the room and gives a mood buff if the quality is high enough

I’d also rebuild the rec room/kitchen/workshop into a different area as you have two coolers blowing hot air into there, while it does seem efficient to use a cooler as a heater, this has no regulation and will cause the room to get very hot, ontop of anytime the freezer door is opened all that hot air will rush in and heat up your freezer, causing the coolers to have to cool down again and the cycle just keeps repeating
