Hi friends
First step I started my project with turning around model and try to find appropriate angel.
After finding the angel that I liked, I thinking to adventure that want to happen in my render.
I love the corten cladding of the university building, so I will not change it, but may I a little change the windows.
The second step is sensation that my render should transfer to viewer, after thinking I came to this conclusion, that portrait the last few days of the year and the joy of starting the new year and happy for the Christmas holidays could be a fascinating subject.
Then my render should be a combination of snow scene and internal heat and happy that exist between the characters of my story (a combination of cold and snow environment and warmth and internal happiness of characters).
students who leave university while they are happy and laughing.

this part is really important. i tried to design some elements and distribute on facade, actually i dont want to change and ignore the purity of the design. or change the boundary of building like pattern number 1 and 5.
at last i chose pattern number 3
here you can see the pattern and 3d models.

I spent some time modeling the elements that will characterize the concept of the student party in the square: exhibitors for paintings and models, interior furnitures of the building, balloons, rollup, information kiosk, light bulbs and flags. I used the colors of the Swedish flag and the university logo: it was very funny!

Although there are no trees in the existing project, I wanted to add 4 birches because I believe that vegetation is one of those key elements that must never be missing in any image.
