The lobby shape and design is alright but some improvements are needed in this lobby. First some of the models are most likely copy & pasted like the tree’s for example, you should make each tree different in any way possible to make it more interesting for the players so it doesn’t look rushed.
You should also try to decorate the area a bit more with more detail and effort put into the background of the lobby like a big hill to make it seem like the players are close to a mountain or a forest close-by.
(I would rate this price around 3,000 —> 5,000 robux depending if you intend to do some changes otherwise as it is right now I would rate it 1,500 - 2,000 robux.)
[I wish you luck with this build and I hope my support was helpful.]
