Okay... I don't mean to "impose"... but that front page takes FOREVER to load.
Consider dividing your content into "excerpts", or "paginating" your posts. Honestly, I didn't feel like waiting around for it to finish loading.
Just my $0.02. ;)
Okay... the image you are using for your header is HUGE. It's dimensions are 4272px by 2848px.
This is ridiculously ridiculous!! It's MUCH too big for a header image.
Try re-sizing your header image in a photo editing program before uploading to your site.
Make it something like 960px by 180px (or whatever you like).
Then, upload that new header image via your WP admin panel.
Adjusting your header image will also help your page loading time... although I'd still follow one of my suggestions above to help it even more.
Good luck!
