Fixed . See attachment.The Metacity theme looks great! Impressive colouring for focused windows.
The only major thing that really stands out as needing a bit of tweaking is the title text. It looks like it could do with dropping down a bit, to make it look vertically centred.
I'm not entirely sure what you mean. At the moment, the shadow drops 1 pixel to the right and 1 pixel down. Do you mean to change the shadow so it drops only 1 pixel down?The concept of a drop-shadow might be better if you put it directly under the text. Presumably, this would have the effect of creating a small shadowy border around all of the text, giving it depth without elevating it a mile above the window
