What do angels look like to you?

So I've been trying to move away from fairies but they keep appearing in my work. I often start off thinking of angels but they somehow always turn into fairies. So, I've been trying harder and finally am beginning to sketch some angels I'm happy with it. My 6 year old son sat down beside this morning we had a conversation:

son: "What is THAT?"
me: "An angel."
son: "No, angels don't look like that."
me: "What do they look like?"
son: "Well, they have a round halo and wear a long shirt. And, their faces are just different than that."
me: "How do you know?"
son: "That's how pictures of them look."
me: "Who drew the pictures?"

anyway, you can see where this is going. So, who really knows what an angel looks like anyway? Be creative, think outside the box! And, I don't want my angel to look like anyone else could have created her!
