Nice work - For no 133 - can you play around with this and give me a few variations. Maybe have a few optione with E with at the top of the spine missing and some with the bottom spine missing, Also can you try lower case.
Please can you try the same upper case text with a splash of colour behind it.
hello client, Please have a look on #45 because it works best on light and dark background !! Its not a simple logo its your "BRAND MARK".So go for something which give you strong recognisation ....My logo was inspired from CISCO network . So if you need any further modifications . Please let me know !!
