Hello.. sorry if I picked up wrong category.

I have been playing around with gtk themes from gnome-look.org, I use default gnome 3 enviroment.

I found this theme: http://computingforgeeks.com/best-gn...an-and-ubuntu/

I followed instructions (well, I didn't, I did exactly the same before I found this instruction but I post it here for you to see what I have done)

Theme is installed but when I activate theme using preinstalled tweak tool, (shell and gtk) it looks just terrible. I did try to use different themes as well but all of them looks terrible.
I believe Im doing something wrong.. I simply put theme in /usr/share/themes. theme is found by tweak tool but when activated, looks like this: Screenshot here

and it supposed to look like this: photo of original vertex theme here

What am I doing wrong please?

thanks in advance
