I always imagined Bleck as square jawed somewhat handsome but aristocratic fellow, not a pretty bishonen as some imagine.
I kinda envision Tas as something aristocratic but still simple enough to allow him to get things done quickly (basically someone who came from lower classes but is trying to act like an aristocrat), also slighty feminine features since many fans mistaked him for a girl when he was revealed.
Currently i'm mostly training, so don't expect much art unless i find them really good
To Rainy: I do not have legs fetish, just think a M&L antagonist should have a better design than the "Male Cackletta Ghost" (his currently design is cool but still too "red herring" for a come back where he would be a much more dangerous antagonist)
