Yes, portrait looks are normal for ROP. You have 3 types of possible looks:
* Full drawing: the guy portrait was available and transformed by our artist
* Blurred face traits: the guy is an historically known character, but unfortunately without valid portrait / picture available (and thus not made by the artist)
* Question mark (internally called 'Potato Heads') : those leaders are generic un-historical leaders needed for play balance. They are usually all of low rank and low values but helpful for avoiding command penalties.
