Project Villa : The Environment shader (W.I.P) (P.2)

Sori :( too busy of works here :( but i keep writing these blogs ^^. Need some critical from everybody.

OK. next is my 2nd sketch and redraw on Sketchup.

===================================================================

2nd sketch is most sketch i like. Sadly , the teacher said " it doesn't look like a villa! i like a streethouse " 

:| firstly, i 'm speechless. Sencondly , i try to explain to him, some things new on my idea. But it's no worth. 

I post the sketchup file here! So that you can improve this ideas, ;) readers !
