I'm with you on that. I did kickboxing and other things for some years, so I've seen some blood from blunt force. Blood dries quite fast and/or gets absorbed by the fibers of the clothing and will then turn into a darker shade of red. Blood has a rather low viscosity. If you beat somebody properly up, there will be lots of little splashes of blood, this looks very "drippy", almost like paint that dropped down. If he's bleeding like that from the mouth, he'd most likely have swallowed some blood coughed it up and all over him. The sweatshirt would look very different at least. If you beat someone up, you'll also have bruises all over his face. Normally you'd see green and blue eyes and bruises on his face, especially his cheeks. Some slightly missed hits always happen, especially when the opponent tries to duck or move away. This looks too "precise" and accurate for some random beat up.
