Sorry for not linking these comments to your submissions. New to the process I put them in the discussion comments below. I am cutting and pasting them so you will receive my comments more easily.
Submission order #1 By OD Thanks for the quick turnaround on a submission. I like what you have done, but would prefer not to cover the globe with BA.
Submission order #2 by OD I like how this brings in two shades of color integrating as it captures the multicultural feel, more can be done to experiment in this area, perhaps with more choices of abstract design. A darker blue or grey would be preferred. The column choice should be more classical, like on a US courthouse. I am more interested in a more elegant font. Good work. Please develop options from this base.
Another thought that I would like to see begin a string of submissions on a different line for comparison purposes would be using the greek column for the letter I, perhaps with a globe dotting it....
Submission order #3 by OD Creative stuff, but too abstract on the BA. Try B&A and a different font. Would like to see other creative letter logos like this still.
I am receiving many positive comments on submission 1, but comments also include that the BA is too overpowering. Can I suggest you try more options with the globe, maybe 3D? and please try "B&A" or just "B". Thanks!
