not bad....having a first pass at it...i'd suggest non bold text or space out your text more for your buttons, right now it's a little unclear, i can read it but it COULD be clearer.
And what res were designing this page with? The nav bar at the bottom isn't really serving it's purpose since i can't really see it "at first glance" with 1280 x 1024.
I also rather liked the first page's background....maybe let it carry through to the other pages as well? cuz I was kinda HIT by the drastic change in color with the rest of the pages. (from very dark, to very light).
but overall it's good stuff keep it up, hope to see more of the manga too!!
