I kinda like the image - not sure how I can describe changes, except more depth detail, perhaps more colors lettering works here, perhaps more pronounced
NEXUS Font Lucida Sans, all cap, same dark blue, but E & U slightly lower size GROUP Font Lucida Sans, all cap, same grey, but smaller size than NEXUS, currently too small and no lines please.
Logo is ok but not perfect. I have decided to go with Dark blue/ grey. May be like credit Suisse or JP Morgan logo
