Hi there, this is a
critique.
I'm not going to pretend to be an expert, i know barely anything about typography, so you should probably take what i say with a pinch of salt. At first, i didn't realise what it was supposed to be. I thought it was just a box with arms and legs and then i realised it was a book. I think the idea is really original and i've not seen anything like it before, but maybe you could make the right side look more like pages? Although i do see that this will be difficult to even notice when the writing is small... just a suggestion though.
Secondly, i think that some of the letters should be moved down a pixel or two because they run into the top of the book making it harder to read. It's still possible, but it's harder.
I think what i'd like to see - and you're obviously capable because your work is fantastic - would be every letter having the book in a slightly different pose with the arms and legs. It would add a little more character, i think.
Keep up the great work
