Well I've seen some of your stuff, Elon.. Twas pretty nice, especially the totem.
If your class is full of dicktards, who can't recognize art - just ignore them. You can draw pretty good, so their fuckin opinion shouldn't mean anything to ya..
So what if some dumbass got more attention. Some people might just admire him, coz he's popular, no matter how fucked up his drawings are. My advice - ask for criticism from people that evaluate the drawing, not the drawer. Tiz fo your own good.
