Fun in the sanatorium

I have stopped working on the Esserveld font for the time being. It has to mature a little bit more. In the meantime I'll do some work on the new font Mokum Sana, derived from the lettering on the gate of the old sanatorium in Zuidlaren, Netherlands. To give you an impression:



These are the lower case characters, next in line is the upper case. Like the original wrought iron letters, they will descend below the baseline. I'm still trying to figure out the best way to do that. Possibly they will rise above the x-height as well, creating room for the diacritics.
Here is the whole set. They look like upper case, but I'm using them as lower case. The upper case will look more like drop caps (like the miniatures in Medieval manuscripts).



And as always: your input is highly valued!
