Technology Centre update!

My revised Technology plan!!

I think i have changed alot of the design -plans wise. Like,look at how ive changed the green house area. And the science labs.But ive got a feedback from this today-- its still rigid looking :(
So im going to change the first floor layout-- I am quite happy with my ground floor layout,so im not going to change it.Except i will make the placement of chairs and tables more random.I dont want it to look too rigid.
