Hello,
I like the changes you've made and the direction this is taking. Can you continue with the concept of 186? Perhaps experiment by putting arrows around the book image instead of just semicircle lines (if you can do two or three arrows circling the logo, I think that might be effective in communicating the "exchange" part of our website). Also, I like the font in 186 but if you can keep experimenting that would be perfect. Thanks!
