There is a minimum level of detail necessary to making a good map, but from Skullcleaver's screenshots it looks like he is somewhere between Marathon and Marathon 2, both of which contained good maps. So, he may have met it. On the other hand, I will suggest that better texturing would help his map far more than adding detail right now.
I do agree with your edit.
