This looks like the truest version of a challenge that exists for professionals...take someone's description of their world and make a map for it. Honestly, I think it's a great idea to push us all to do something that a pro might do rather than how I (and I assume many others) just do up something random in order to experiment with techniques and styles. I'd like to see 50 or more entries for this just to give us all a bit of pro-style experience if for no other reason than to justify to our own selves that we can do it. Thumbs up from me.
