It's a great theme with many improvements.
I'll just note some of the things I think should be reviewed.

In the home page, the little minus sign on the right side of the sections doesn't fit well with the rest of the page design. It can be replaced with a simple "-" or removed completely.

The descriptions above the avatars break the layout. It should be disabled or have a character limit.

The alignment in the "New Posts" and "Today's Posts" section isn't great.
While it could look like that:

The number of thanks a user received should be removed if the feature was removed.

There's no need for a buddy list. We have the irc, which purpose is buddying.

At the top of the thread, near the thread title, there should be an indication of the section the thread was posted in.

The items at the top can be merged in the bar. Also, let's note that there's no need for the "Home" and "Forums" links in the bar. The "Search" and "Donate" buttons should also be re-added.

The control panel regained all its features but it doesn't look as good as the previous one.
It might be because of the images.
Old one:
New one:

Same thing for the contact, the images do not fit well.

That should be it. By the time I'm posting some of the things I've mentioned might have already been corrected.

Thanks for your hard work Jayro!
