This thread is where to post all feedback for the theme: SoulSilver Luigia. I recommend using the same structure that I am using.
Overall: In my opinion, it would be good for those who don't like dark colors, although I am not one of those people. The smaller font looks good, although it can become annoying after a while (especially if you are used to the font size of "Site Theme".
Pros:
-Internal Site Links (Unlike the "Site Theme")
-Nice "Clean" look
-Can compete with "Site Theme" for Default Theme
-Gradiant Background for Quotes
Cons:
-Not enough contrast between visited links and background, and a few other situations.
-Icons for "Forums Read", and "New Posts" don't contrast enough, so it isn't obvious which forums have new posts.
-User Title and Badges are not directly Below the username.
-Age/Gender not shown in posts ("Site Theme" dosn't show Gender Either)
-Text Color in "Title" textbox when replying to a message dosn't have enough contrast
[Edit]: I have added a poll with likely options.
