Tunnel through the sea"/>



Pretty good, but I'd leave out the fence in the middle.
Najaa pretty small, if you look up you see glass right in front of your eyes. The fence I would also leave out, these (decorativlos) rails also.
Dislike!
Do you need one of these? I would have used colored glass.
@WarriorCats I think the rail is not supposed to be a decoration but because there are no drive rails they seem useless
I think it's cool
