I especially like the birds "flying" out of the trees, towards the right. Kind of funny too, because I didn't even notice the birds until I had picked the header photo and adjusted the sidebar.
Note: I sound all tech-y and professional blogger-y, but in reality Blogger just makes it really easy. Try it! It takes a little fiddling and whatnot, but the new "make as many changes as you want but it won't save until you say so" feature makes it much less painless than before.
