Love the creative thinking. Really like the use of different fonts and colors for the two words. Unfortunately the color choice and the graphic underneath are conveying water to me. And while our office building is next to a beautiful canal, I don't think that's what we want to focus on.
Did you circle the c in architecture to bridge the two words "Arc" and "Architecture"? If that's the case it's very clever, but I fear the average person probably won't get it. We use Online Arc like a nickname - we answer the phone Online Architecture but in an email to a client we might refer to ourselves as Online Arc. Also the big O wasn't grabbing us. In short, while we appreciated the creative approach, it's just not in the right direction for us.
The idea here is that you guys are an idea "factory," hence the gear image incorporated into your initials. Colors, type arrangement, etc. can be changed if you would like to see any revisions.
