#22 ... #26: We love the tone you choose, it's simple, elegant and friendly. We like the font chosen and the details in bright green. May be the problem we see is that the icon is too merged with the name, and that makes difficult to use it alone.
#22: The green tail was a beautiful improvement from #23 (a bit too similar to the Amazon smile?), how could it be part on the isolated icon?
#25, #26: We don't like too much to highlight letters inside the name, it destroys the ambiguity of "book+evocation". But we like the idea of small circles to suggests "evocation".
#5, #6: They were discarded because we don't like to use the letter "E" as an icon, it's too generic for "e-lectronic" words, and it's very far from the image of "book+evocation".
#27: Similar reasons to #5 and #6. The comic globe suggests chatting and communication, not individual dreaming and evocation.
