Glad to see this one being done. I assume you will be getting TGC2. So with almost everything done correctly in this version, maybe the new themes/objects help you get your true vision when it comes out. I would rather play a well done RCR with GNCD limitations then one that looks good but is missing everything else(quite a few of those by other designers).
Also with the new game in mind keep it to specs like you did with Medinah. A lot of the designers are artificially tricking up some RCRs to make them harder(firmness, false elevations, etc). If the top players complain it's too easy you can always release the max everything later.
