A -- Kudos! #78 through #81 provide a strikingly stylish set of logos that I very much enjoy. Let me give you some first impressions. The symbol in #78 is elegant all by itself. I think this is such a strong design. I wonder what it would look like against a white background. I believe that your intention was that the extra flourish can be read by itself as a lowercase 'h' as well as an uppercase 'H' when it borrows the left downstroke and lower arc of the 'R'. I'm wondering if slight tweak might emphasize the latter aspect: Extend the length of the loop of the 'h' and rotate it counterclockwise a little bit to be more parallel with the 'R' downstroke. Without seeing it, I think that would increase the appeal of this (already strong) design to me. (My initial reaction to the design was why such a small and lowercase 'h' -- which was distracting given that I couldn't see the 'H' for awhile.)
I really like the frame that you've added in #79, too. Both #78 and #79 work so it's hard for me to decide which I prefer. Re #79, I wonder if maybe the white stroke around the 'R' and 'h' is a bit too strong.
The two-color symbol is nice in the pair #80 and #81. I might prefer the less colorful #78 and #78 but it is hard to say right now. I will be admiring both pairs for awhile to see what might preferences are then! Do you think the grey/gold combination might work better that the dark brown? I'd be interested in seeing perhaps a more subtle pair for a softer look.
Again, bravo. Your ideas continue to impress. -- Roger
