Hi! Thanks a lot for your feedback. I've uploaded some revisions for you. One thing I would say about the concern about the lettermark looking like only an R -- many quite successful and memorable logos have a clever twist on them that, at first glance, people don't recognize. The trick is, once they do recognize it, that makes the logo that much more memorable, which is a key characteristic. That's not to belittle your concerns at all. Just trying to bring another perspective. I strive to make my logos memorable, and hiding an image in a logo is one way to do that.
Take the Fedex logo. Did you ever notice the arrow in the negative space between the second E and the X?
