I've done some avatar art, and it's a lot of fun. I'm at my best with scanned pencil work.
I've got a deviantArt page, but if you're too lazy to poke around there, here's a couple of samples…
Most recent male…
It scanned a bit funny, so it's a little odd-looking.
But anyway,
here's the most recent female.
And I've done one pair commission, though it was a good bit earlier than those two pieces up there. It looks like this.
I don't do much in the way of shading. Like, shadows. But I'm working on it.
My mode price for work like this has been 10,000 gold. I like to leave it up to the recipient to decide what it's worth/what they can afford once s/he sees the completed piece.
If you are interested in having me draw for you, please let me know in a reply here or in a private message.
