I agree with the previous comment. The layout goes very well with the comic, especially concerning your color pallet.
The only things you might want to consider adding are an RSS feed and/or an email subscription option at the bottom. The RSS feed button could easily go right next to your Facebook and Twitter buttons. Just a suggestion though.
The other thing you might want to take into consideration is whether or not an entire individual panel can be viewed in its entirety on a standard laptop (I cannot see a whole panel top-to-bottom on my 15" screen). Again, just a suggestion.
Overall, the page looks great! Also, I like the "He's going to jump!" comic. Very clever.
