It's not bad, but as Andrew suggested, it would be much better if the camera is in the same position. What you can do is set up a tripod on the opposite side of the drawing so when you take the picture, it's upside down but you can later flip it. Have her tape the drawing down so it doesn't move on the table. (A soft tape like masking tape would work well as you don't want to damage the paper. Stick if a few times on your clothes to help it lose it's stickiness so you can peal it off easier when done.)
It takes a while to get used to the drawing being taped down as you have to get used to turning and moving yourself to draw and not the paper, but it makes a huge difference in the video. If taping down doesn't seem like a great idea, you can leave markers on the table to know where to place the drawing so the pictures will still line up.
You don't have to do any of the above, it's just my suggestions. If you come up with your own solution or just want to leave it as is, that's fine too.
Side note: the dragon is very good! I love the eye
