The Layout is nice..! but try to change the devil picture to a friendly picture. hope to see more layouts with you..
Your first design is great except for the devil looking head. Not sure why that is in there. Your second design is fantastic. I love it. Problem is the twitter bird. You have to understand that anime/manga fans are not so concerned with Twitter. If you want to put a place for a twitter link or a 'follow us' type of image, it will have to blend in with the design. Find a few fantasy geese that flock together or something along those lines and make a cute button and then say 'follow us on twitter' or something along those lines. Web 2.0 and fantasy never mixes well. But overall good.
Site #1 : It looks good except the devil on header and the right side of that devil have much empty space. Site #2 : It's good (better than #1), but I feel the logo on header haven't much strong power. Site #3 : It's nice design but I don't feel comfort with red color. I feel that color too strong for my eyes. E-book cover : Great design ! If I can choose, I'll choose site #2 and your ebook cover. But overall good. Great job !
Honestly...i didn't liked at very much..colors are not good,that devil in first pic is useless & is looking awkward...so basically there's a scope of improvement
