Thank you for your submission. Original, playful, and modern colors. You read the briefing well. Only remark is that the word audit is a bit in the background due to the lighter font and the grey. I am also curious how it looks if emailaudit or emailaudit.com is written in small caps.
I still like #37 and the variants #37, #38 and #39. But they are beginning to look a bit flat amongst the other designs. Perhaps you can make #37 more sophisticated with a subtle gradient or a second color?
I have one last request. I like the cleaner hand in #86, but it doesn't fit the website. Can you place the text a little higher in #86, so it is vertically more in the middle. Then I can vertically align the logo text with the menu buttons.
