Good for you, I don't have any real life friends or family that communicate on deviantart with me because they either don't have an account, or they're my brother.
I'm the only one out of my family to really get into art and stayed like that, my mum can draw, but she rarely does it. My brother seemed to have developed an interest with deviantart, though I have no idea what he does on it, he doesn't like me watching him.
