After I had placed my first concept version of Silvan Elven King Thranduils Halls on my homepage ('Hobbit' on www.henj.nl), I received quite some comments on them. Some, however, were discussing a different kind of soil and thus tectonic structure. Personally, I find this 'hanging root' version a bit odd and unfitting for the information that Tolkien gives us over the entrance of the Mirkwood hills (next to his simple illustration). Anyway - I took a few days and went on doodeling roots .... So have a look at Version I to compare. It certainly will not be the last concept of the caves I am going to produce for I am still far from satisfied.
