And actually I don't see anything strange or wrong in this kind of attitude. I fell asleep with my siblings a million of times and, well, it generally ends with a foot on my face or a knees in my stomach- but untill that very moment it is just nice and comfortable and peacefull. I don't understand why people need to see THAT kind of implications in a gesture that just means family and affection. They are just sweet and, you know, very brotherly :3
I bet that Scru is drooling a lot, though. He just looks the kind of person that can do evil things even while sleeping. I can foretell that Floyds will fling him on the floor at any moment.
Super awsome picture, by the way, you are talented! (also, sorry for the grammar, my english sucks :/ )
