Some screenshots of the rest of the room would be nice. Yes, the spawn rooms function similar, but spawning everyone on one side of a room and having them click buttons to choose a class isn't really what Pecon's server is widely known for. I'd call that more of a proven method, like constructing a device for sitting on as a platform held above the ground by 4 legs, and a flat part attached to one side extending upward to lean back into. If you want to stick to it, fine. If you want to make it more comfortable or stylish, great. If you want to come up with something new, go for it.
That said, after looking at the new spawn rooms, you could branch out a bit. Lay out the buttons in different ways, change the shape of them, put your own creativity into it. Additionally, I'd advise against focusing so heavily on the spawn rooms in your media as long as they are so similar to Pecon's (You don't print "It has 4 legs and you can sit on it" on the box of your chair design.). Give more information about the classes, the bosses, and as I said earlier, post more pictures of the bedroom. Unless of course your intention of making your server like Pecon's shows there, too, in which case, you may want to put off on advertising.
