This was in The Snowmen when she was hiding behind the TARDIS on the cloud. I should have drawn the background, but I am crap at backgrounds. So this is just my pencil/graphite drawing of her because she is cool.
She is so lovely, I can't wait to see more of her And you drew a great portrait, very recognizable. I find hair the most impressive of all. It's obvious you didn't pay as much attention to the neck as you did to her face which I get, necks suck
One tip: Don't give up on drawing background because you suck at it, I'm really bad at painting backgrounds myself (you're a lot better artist than me so you probably have higher standards), but since I've started drawing/painting backgrounds on every single one of my drawings/paintings I really improved. Don't give up
I've checked out the rest of your gallery, you've really improved since you joined the site. I love your bird art btw, I love the way you draw the feathers.
