Main space modelling / landscape
1st model with only surface and roof was not working
2nd modified model with thickness and roof ( I think it's glass)
It's really looks like stadium.
sort of struggling created soft landscape, because paths are not properly leveled.
But trying to creat more landscape in between path and cells.
and move on.

yes, it really looks like a stadium - but an interesting one! keep it, and keep working on it. modelling is really coming along well - am interested to see how all of the detail in the model translates into the drawings.
some of the views are great - pick one for tomorrow that you can apply material to, and start doing a proper render.
