Thanks so much for your work. The acronym we use to refer to our organization is RCWD so that would need to be reflected in your designs. Sorry if this was unclear from my design brief.
Sure, here is my general feedback. #7 is too abstract for our purposes because we are a government entity. I'd be interested in seeing any of the others with the RCWD incorporated. Linking the letters together in #5 is an interesting idea. I think I like the font used in #6 and #8 better though.
I really like #12, but am not sure about running a line through the letters. It looks as though you are crossing them out. Do you have any other thoughts for this one?
