Keep in mind that I know less than nothing about coding/website making/graphic design, but. I'm using IE, and I think it looks really nice! The quirks you mentioned are not present as I see it. I do think maybe there should be more separation between the boxes describing each comic. Also, have you considered putting something different on the front page of Cuanta Vida after a while, so that people wanting to read it for the first time don't get spoilered by the final page immediately?
