An oekaki I made for the Harry Potter theme on "cimetery board" : "create your own HP character". There was a "hat's choice" test linked, I did it and it said I was a Ravenclaw, so I drew one XD. As he seems older than many HP chars he has to be a dean or something (not a teacher, except if "yaoi" can be considered a sorcery subject...)

But I didn't use a good reference for the costume, that's why there are many mistakes (I think the real colours are blue and gold for the tie, for instance... and there must be a pullover on the shirt... Well let's say he lost some clothes while doing suspicious things in the forbidden woods - he looks suspicious anyway XD.)

Shi-painter, about 3h o__O (yeah... I thought it would be easier to draw plain black hair like that but actually it's not because you have to be more precise >___<...)
