Mantle...(or Shelf)Trouble

Help, please!

After reading Centsational Girl's Autumn Mantel + Link Party post, I realized my mantel...uh...shelf isn't all it could be. Basically, it's all decor I've gathered when it was super cheap, stuff we got for the wedding and what was free and I plopped it down.
Make sure to check Censational Girl's site out. Great ideas posted by other fellow bloggers are shared at the bottom of the post.

What could I invest in for this space, to swap out each season? Ideas please! Please check out this post here, to see what else I have to work with.

What could I put in the frames? Are the frames even right for this space? Should I get a mirror? Layer more picture frames and framed artwork?

I do not like the color scheme anymore. 

I like decorating with the natural elements of fall and the colors...not too coordinated or primitive and not too untraditional. Wow...I am picky.

I like a lot of depth and layering. Different heights, finishes, but also keeping simple as well. Something like this...from Centsational Girl's Transitioning Your Home For Fall post.

We are getting closer to my style here. I think I am sold on the lantern and I even spotted some awesome ones at Gordman's and on Target's website.
