Thanks Kimski for the helpful feedback!
I will submit soon new variations with requested changes.
Please let me know, if the idea of using logo instead of the letter "O" your request or is it from the designer ideaz99? (several others using mark instead of the letter "O" as well, so maybe I'm wrong about designer's name)
If is yours then would be no problem, but if someone else used it, before you requested, then I will not be able to apply your request.
Thanks for clarification.
Sincerely,
Bordo
