Would it be possible to have the scales for a dragonblooded sorcerer spreading across more than just the face, like along the back, shoulders, or lower ribs? Just something that would seem to fit well for the character type.
But I would add something, Gith facial marks seem to be scales of some sort? I would appreciate it if Draconic sorcerer scales replaced them, instead of being placed on top of them... its real damn cluttered looking.
I also think the scales should cover more of the body in addition to the face.
Also, I agree with the comment about how it might help if the scales replaced the Gith facial markings instead of getting layered over them. I don't know how easy that would be, though.
