Heard about this place on distrowatch and I have an idea for some parts of a default theme (I didn't like the default theme much either)

Window Decoration - I couldn't find a good window decoration theme for KWin so I modified several elements from 2 different window decoration themes and put them together. This was the result:

Maybe you could do something similar.

Desktop Theme - My favorite Desktop Theme for Plasma Desktop is Oxyzone

Maybe you could do something similar to that.

Style- QtCurve provides a good engine. I used something based on their Agua and Agua II presets. This could be used as the default engine maybe.

I want the best theme windows Zorin Os. http://zorin-os.com/gallery.html

Fatiga: I can tell you that the current work on the light version is similar to Zorin in color choices (the color pallette have already been picked and you can see it on the blog at vdesign.kde.org ) and shapes so you'll probably be very pleased.

Thank you very much Jensreuterberg, you done me very happy, I hope the buttons off, maximized, minimized and are also similar in shape and size. Greetings from Spain.

No they are not.

Just to be clear the reason why they look similar is due to colors and the fact that they follow a similar path of design as we.

But to copy them would be rather boring.

As long as the buttons are not round i'm ok with everything ;P
Just curious are you interested in new ideas for the theme or have you already decided how it will look like.
