A new look

Can you tell it's my day off? I wanted to give The Seventh Planet a nicer look, so I made a few changes.

• The new banner is from this free site. Thank you DHester for posting such nice headers. He has a lot of interesting images of shattered glass.
• I made the digg button less conspicuous. Now people won't know that I'm getting 0 diggs. =)
• The widgets are rearranged a little and the colors are all different.
• I'm using Arial font now. I tried out a serif font but I'm back to my old favorite.
  

Please let me know what you think! I know very little about web design and want some suggestions.
