Wazakita. Did Dianthus and Christmas Rose. Not a big fan of Christmas Rose but I personally don't find any girl who looks better than Dianthus design wise.

Sasayuki (Sinclairiana, FKG prequel manga) and Wazakita (Dianthus/Christmas Rose) are the obvious ones.

Kurasuke is the easy personal favorite for doing Daisy, Olive, and Lesser Celandine. And is working on an HRPG.
